NCP163

250 mA, Ultra-Low Noise

and High PSRR LDO

Regulator for RF and

Analog Circuits

The NCP163 is a next generation of high PSRR, ultra−low noise

LDO capable of supplying 250 mA output current. Designed to meet

the requirements of RF and sensitive analog circuits, the NCP163

device provides ultra−low noise, high PSRR and low quiescent

current. The device also offer excelent load/line transients. The

NCP163 is designed to work with a 1 mF input and a 1 mF output

ceramic capacitor. It is available in two thickness ultra−small 0.35P,

WLCSP Packages, XDFN4 0.65P and industry standard SOT23−5L.

NCP163

APPLICATIONS INFORMATION

General

The NCP163 is an ultra−low noise 250 mA low dropout

regulator designed to meet the requirements of RF

applications and high performance analog circuits. The

NCP163 device provides very high PSRR and excellent

dynamic response. In connection with low quiescent current

this device is well suitable for battery powered application

such as cell phones, tablets and other. The NCP163 is fully

protected in case of current overload, output short circuit and

overheating.

Input Capacitor Selection (CIN)

Input capacitor connected as close as possible is necessary

for ensure device stability. The X7R or X5R capacitor

should be used for reliable performance over temperature

range. The value of the input capacitor should be 1 mF or

greater to ensure the best dynamic performance. This

capacitor will provide a low impedance path for unwanted

AC signals or noise modulated onto constant input voltage.

There is no requirement for the ESR of the input capacitor

but it is recommended to use ceramic capacitors for their low

ESR and ESL. A good input capacitor will limit the

influence of input trace inductance and source resistance

during sudden load current changes.

Output Decoupling (COUT)

The NCP163 requires an output capacitor connected as

close as possible to the output pin of the regulator. The

recommended capacitor value is 1 mF and X7R or X5R

dielectric due to its low capacitance variations over the

specified temperature range. The NCP163 is designed to

remain stable with minimum effective capacitance of 0.7 mF

to account for changes with temperature, DC bias and

package size. Especially for small package size capacitors

such as 0201 the effective capacitance drops rapidly with the

applied DC bias. Please refer Figure 47.

Figure 47. Capacity vs DC Bias Voltage

There is no requirement for the minimum value of

Equivalent Series Resistance (ESR) for the COUT but the

maximum value of ESR should be less than 2 W. Larger

output capacitors and lower ESR could improve the load

transient response or high frequency PSRR. It is not

recommended to use tantalum capacitors on the output due

to their large ESR. The equivalent series resistance of

tantalum capacitors is also strongly dependent on the

temperature, increasing at low temperature.

Enable Operation

The NCP163 uses the EN pin to enable/disable its device

and to deactivate/activate the active discharge function.

If the EN pin voltage is <0.4 V the device is guaranteed to

be disabled. The pass transistor is turned−off so that there is

virtually no current flow between the IN and OUT. The

active discharge transistor is active so that the output voltage

VOUT is pulled to GND through a 280 W resistor. In the

disable state the device consumes as low as typ. 10 nA from

the VIN.

If the EN pin voltage >1.2 V the device is guaranteed to

be enabled. The NCP163 regulates the output voltage and

the active discharge transistor is turned−off.

The EN pin has internal pull−down current source with

typ. value of 200 nA which assures that the device is

turned−off when the EN pin is not connected. In the case

where the EN function isn’t required the EN should be tied

directly to IN.

Output Current Limit

Output Current is internally limited within the IC to a

typical 700 mA. The NCP163 will source this amount of

current measured with a voltage drops on the 90% of the

nominal VOUT. If the Output Voltage is directly shorted to

ground (VOUT = 0 V), the short circuit protection will limit

the output current to 690 mA (typ). The current limit and

short circuit protection will work properly over whole

temperature range and also input voltage range. There is no

limitation for the short circuit duration.

Thermal Shutdown

When the die temperature exceeds the Thermal Shutdown

threshold (TSD − 160°C typical), Thermal Shutdown event

is detected and the device is disabled. The IC will remain in

this state until the die temperature decreases below the

Thermal Shutdown Reset threshold (TSDU − 140°C typical).

Once the IC temperature falls below the 140°C the LDO is

enabled again. The thermal shutdown feature provides the

protection from a catastrophic device failure due to

accidental overheating. This protection is not intended to be

used as a substitute for proper heat sinking.

Power Dissipation

As power dissipated in the NCP163 increases, it might

become necessary to provide some thermal relief. The

maximum power dissipation supported by the device is

dependent upon board design and layout. Mounting pad

configuration on the PCB, the board material, and the

NCP163

www.onsemi.com

ambient temperature affect the rate of junction temperature

rise for the part.

The maximum power dissipation the NCP163 can handle

is given by:

PD(MAX) +ƪ125oC*TAƫ

qJA

The power dissipated by the NCP163 for given

application conditions can be calculated from the following

Reverse Current

The PMOS pass transistor has an inherent body diode

which will be forward biased in the case that VOUT > VIN.

Due to this fact in cases, where the extended reverse current

condition can be anticipated the device may require

additional external protection.

Power Supply Rejection Ratio

The NCP163 features very high Power Supply Rejection

ratio. If desired the PSRR at higher frequencies in the range

100 kHz – 10 MHz can be tuned by the selection of COUT

capacitor and proper PCB layout.

Turn−On Time

The turn−on time is defined as the time period from EN

assertion to the point in which VOUT will reach 98% of its

nominal value. This time is dependent on various

application conditions such as VOUT(NOM), COUT, TA.

PCB Layout Recommendations

To obtain good transient performance and good regulation

characteristics place CIN and COUT capacitors close to the

device pins and make the PCB traces wide. In order to

minimize the solution size, use 0402 or 0201 capacitors with

appropriate capacity. Larger copper area connected to the

pins will also improve the device thermal resistance. The

actual power dissipation can be calculated from the equation

above (Equation 2). Expose pad can be tied to the GND pin

for improvement power dissipation and lower device

temperature.
