Datasheet

1 General Description

The AS1358 / AS1359 are ultra-low-noise, low-dropout linear

regulators specifically designed to deliver up to 150/300mA

continuous output current, and can achieve a low 140mV dropout for

300mA load current. The LDOs are designed and optimized to work

with low-cost, small-capacitance ceramic capacitors.

The devices are available as the standard products listed in Table 1.

An integrated P-channel MOSFET pass transistor allows the devices

to maintain extremely low quiescent current (40µA).

The AS1358 / AS1359 uses an advanced architecture to achieve

ultra-low output voltage noise of 9µVRMS and a power-supply

rejection-ratio of better than 80dB (up to 10kHz).

The AS1358 / AS1359 requires only 1µF output capacitor for stability

at any load. When the LDO is disabled, current consumption drops

below 500nA.

The devices are available in a TSOT23 5-pin package.

AS1358 / AS1359

Datasheet - Detailed Description

8 Detailed Description

The AS1358 / AS1359 are ultra-low-noise, low-dropout, low-quiescent current linear-regulators specifically designed for space-limited

applications. The devices are available with preset output voltages from 1.5V to 4.5V in 50mV increments.

These devices can supply loads up to 150mA / 300mA. As shown in Figure 18, the AS1358 / AS1359 consist of an integrated bandgap core and

noise bypass circuitry, error amplifier, P-channel MOSFET pass transistor, and internal feedback voltage-divider.

Figure 18 shows the block diagram of the AS1358 / AS1359. It identifies the basics of a series linear regulator employing a 0.5 (typ) P-Channel

MOSFET as the control element. A stable voltage reference (REF in Figure 18) is compared with an attenuated sample of the output voltage.

Any difference between the two voltages (reference and sample) creates an output from the error amplifier that drives the series control element

to reduce the difference to a minimum. The error amplifier incorporates additional buffering to drive the relatively large gate capacitance of the

series pass P-channel MOSFET, when additional drive current is required under transient conditions. Input supply variations are absorbed by the

series element and output voltage variations with loading are absorbed by the low output impedance of the regulator.

The AS1358 / AS1359 deliver preset output voltages from 1.5V to 4.5V, in 50mV increments (see Ordering Information on page 15).

The output voltage is fed back through an internal resistor voltage-divider connected to pin OUT. An external bypass capacitor connected to pin

BYPASS reduces noise at the output. Startup time is minimized by internal power-on circuitry which pre-charges CBYPASS. Additional blocks

include a current limiter, thermal sensor, and shutdown logic.

Datasheet - Application Information

9 Application Information

9.1 Dropout Voltage

Dropout is the input to output voltage difference, below which the linear regulator ceases to regulate. At this point, the output voltage change

follows the input voltage change. Dropout voltage may be measured at different currents and, in particular at the regulator maximum one. From

this is obtained the MOSFET maximum series resistance over temperature etc. More generally:

(EQ 1)

Dropout is probably the most important specification when the regulator is used in a battery application. The dropout performance of the

regulator defines the useful “end of life” of the battery before replacement or re-charge is required.

Figure 19. Graphical Representation of Dropout Voltage

Figure 19 shows the variation of VOUT as VIN is varied for a certain load current. The practical value of dropout is the differential voltage (VOUT-

VIN) measured at the point where the LDO output voltage has fallen by 100mV below the nominal, fully regulated output value. The nominal

regulated output voltage of the LDO is that obtained when there is 500mV (or greater) input-output voltage differential.

9.2 Efficiency

Low quiescent current and low input-output voltage differential are important in battery applications amongst others, as the regulator efficiency is

directly related to quiescent current and dropout voltage. Efficiency is given by:

Efficiency = % (EQ 2)

9.3 Power Dissipation

Maximum power dissipation (PD) of the LDO is the sum of the power dissipated by the internal series MOSFET and the quiescent current

required to bias the internal voltage reference and the internal error amplifier, and is calculated as:

Watts (EQ 3)

Internal power dissipation as a result of the bias current for the internal voltage reference and the error amplifier is calculated as:

Watts (EQ 4)

Total LDO power dissipation is calculated as:

Watts (EQ 5)

9.4 Junction Temperature

Under all operating conditions, the maximum junction temperature should not be allowed to exceed 125ºC (unless the data sheet specifically

allows). Limiting the maximum junction temperature requires knowledge of the heat path from junction to case (JCºC/W fixed by the IC

manufacturer), and adjustment of the case to ambient heat path (CAºC/W) by manipulation of the PCB copper area adjacent to the IC position.

9.5 Explanation of Steady State Specifications

9.5.1 Line Regulation

Line regulation is defined as the change in output voltage when the input (or line) voltage is changed by a known quantity. It is a measure of the

regulator’s ability to maintain a constant output voltage when the input voltage changes. Line regulation is a measure of the DC open loop gain

of the error amplifier. More generally:

Line Regulation = and is a pure number (EQ 8)

In practise, line regulation is referred to the regulator output voltage in terms of % / VOUT. This is particularly useful when the same regulator is

available with numerous output voltage trim options.

Line Regulation = % / V (EQ 9)

9.5.2 Load Regulation

Load regulation is defined as the change of the output voltage when the load current is changed by a known quantity. It is a measure of the

regulator’s ability to maintain a constant output voltage when the load changes. Load regulation is a measure of the DC closed loop output

resistance of the regulator. More generally:

Load Regulation = and is units of ohms ()(EQ 10)

In practise, load regulation is referred to the regulator output voltage in terms of % / mA. This is particularly useful when the same regulator is

available with numerous output voltage trim options.

Load Regulation = % / mA (EQ 11)

9.5.3 Setting Accuracy

The regulator is supplied pre-trimmed, so that the output voltage accuracy is fully defined in the output voltage specification.

9.5.4 Total Accuracy

Away from dropout, total steady state accuracy is the sum of setting accuracy, load regulation and line regulation. Generally:

Total % Accuracy = Setting % Accuracy + Load Regulation % + Line Regulation % (EQ 12)

9.6 Explanation of Dynamic Specifications

9.6.1 Power Supply Rejection Ratio (PSRR)

Known also as Ripple Rejection, this specification measures the ability of the regulator to reject noise and ripple beyond DC. PSRR is a

summation of the individual rejections of the error amplifier, reference and AC leakage through the series pass transistor. The specification, in

the form of a typical attenuation plot with respect to frequency, shows up the gain bandwidth compromises forced upon the designer in low

quiescent current conditions. Generally:

PSSR = dB using lower case to indicate AC values (EQ 13)

Power supply rejection ratio is fixed by the internal design of the regulator. Additional rejection must be provided externally.

Datasheet - Application Information

9.6.2 Output Capacitor ESR

The series regulator is a negative feedback amplifier, and as such is conditionally stable. The ESR of the output capacitor is usually used to

cancel one of the open loop poles of the error amplifier in order to produce a single pole response. Excessive ESR values may actually cause

instability by excessive changes to the closed loop unity gain frequency crossover point. The range of ESR values for stability is usually shown

either by a plot of stable ESR versus load current, or a limit statement in the datasheet.

Some ceramic capacitors exhibit large capacitance and ESR variations with temperature. Z5U and Y5V capacitors may be required to ensure

stability at temperatures below TAMB = -10ºC. With X7R or X5R capacitors, a 1.0µF capacitor should be sufficient at all operating temperatures.

Larger output capacitor values (2.2µF max) help to reduce noise and improve load transient-response, stability and power-supply rejection.

9.6.3 Input Capacitor

An input capacitor at VIN is required for stability. It is recommended that a 1.0µF capacitor be connected between the AS1358 / AS1359 power

supply input pin VIN and ground (capacitance value may be increased without limit subject to ESR limits). This capacitor must be located at a

distance of not more than 1cm from the VIN pin and returned to a clean analog ground. Any good quality ceramic, tantalum, or film capacitor may

be used at the input.

9.6.4 Noise

The regulator output is a DC voltage with noise superimposed on the output. The noise comes from three sources; the reference, the error

amplifier input stage, and the output voltage setting resistors. Noise is a random fluctuation and if not minimized in some applications, will

produce system problems. The AS1358/9 architecture provides enhance noise reduction when an external 10nF capacitor is connected between

Bypass and Output pins, and 1µF connected as the output capacitor.

The leakage current going into the BYPASS pin should be less than 10nA. Increasing the capacitance slightly decreases the output noise.

Values above 0.1µF and below 0.001µF are not recommended.

9.6.5 Transient Response

The series regulator is a negative feedback system, and therefore any change at the output will take a finite time to be corrected by the error

loop. This “propagation time” is related to the bandwidth of the error loop. The initial response to an output transient comes from the output

capacitance, and during this time, ESR is the dominant mechanism causing voltage transients at the output. More generally:

Units are Volts, Amps, Ohms. (EQ 14)

Thus an initial +50mA change of output current will produce a -12mV transient when the ESR=240m. Remember to keep the ESR within

stability recommendations when reducing ESR by adding multiple parallel output capacitors.

After the initial ESR transient, there follows a voltage droop during the time that the LDO feedback loop takes to respond to the output change.

This drift is approximately linear in time and sums with the ESR contribution to make a total transient variation at the output of:

Units are Volts, Seconds, Farads, Ohms. (EQ 15)

Where:

CLOAD is output capacitor

T = Propagation delay of the LDO

This shows why it is convenient to increase the output capacitor value for a better support for fast load changes. Of course the formula holds for

t < “propagation time”, so that a faster LDO needs a smaller cap at the load to achieve a similar transient response. For instance 50mA load

current step produces 50mV output drop if the LDO response is 1usec and the load cap is 1µF.

There is also a steady state error caused by the finite output impedance of the regulator. This is derived from the load regulation specification

discussed above.

9.6.6 Turn On Time

This specification defines the time taken for the LDO to awake from shutdown. The time is measured from the release of the enable pin to the

time that the output voltage is within 5% of the final value. It assumes that the voltage at VIN is stable and within the regulator Min and Max limits.

Shutdown reduces the quiescent current to very low, mostly leakage values (<1µA).

9.6.7 Thermal Protection

To prevent operation under extreme fault conditions, such as a permanent short circuit at the output, thermal protection is built into the device.

Die temperature is measured, and when a 160ºC threshold is reached, the device enters shutdown. When the die cools sufficiently, the device

will restart (assuming input voltage exists and the device is enabled). Hysteresis of 15ºC prevents low frequency oscillation between start-up and

shutdown around the temperature threshold.
