XC6601 Series ETR0335_006 Low Voltage Input LDO Voltage Regulator with Soft-Start Function GENERAL DESCRIPTION The XC6601 series is a low voltage input CMOS LDO regulator which provides highly accurate (20mV) outputs and can supply current efficiently due to its ultra low on-resistance even at low output voltages. The series is ideally suited to the applications which require very low dropout voltage operation and consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a fold back circuit, a thermal shutdown (TSD) circuit, an under voltage lock out (UVLO) circuit, soft-start circuit and a phase compensation circuit. Output voltage is selectable in 0.05V increments within a range of 0.7V to 1.8V using laser trimming technology and ceramic capacitors can be used for the output stabilization capacitor (CL). The over current protection circuit (the current limiter and the fold back circuit) as well as the thermal shutdown circuit (the TSD circuit) are built-in. These two protection circuits will operate when either the output current reaches the current limit level or the junction temperature reaches the temperature limit level. With the built-in UVLO function, the regulator output is forced OFF when the voltage level at the VBIAS pin or the VIN pin falls below the UVLO voltage level. With the soft-start function, the inrush current from VIN to VOUT for charging CL at start-up can be reduced and makes the VIN stable. The CE function enables the output to be turned off and the series to be put in stand-by mode resulting in greatly reduced power consumption. At the time of entering the stand-by mode, the series enables the electric charge at the output capacitor (CL) to be discharged via the internal auto-discharge switch which is located between the VOUT pin and the VSS pin. As a result the VOUT pin quickly returns to the VSS level.

The N-channel MOSFET which is connected to the VOUT pin is then driven by the subsequent output signal. The output voltage at the VOUT pin is controlled & stabilized by a system of negative feedback. VBIAS pin is power supply pin for output voltage control circuit, protection circuit and CE circuit. When output current increase, the VBIAS pin supplies output current also. VIN pin is connected to a driver transistor and provides output current. In order to obtain high efficient output current through low on-resistance, please take enough Vgs (=VBIAS - VOUT(T)) of the driver transistor. Output current triggers operation of constant current limiter and fold-back circuit, heat generation triggers operation of thermal shutdown circuit, the driver transistor circuit is forced OFF when VBIAS or VIN voltage goes lower than UVLO voltage. Further, the IC's internal circuitry can be shutdown via the CE pin's signal. Figure1: XC6601A series <Low ESR Capacitor> With the XC6601 series, a stable output voltage is achievable even if used with low ESR capacitors, as a phase compensation circuit is built-in. The output capacitor (CL) should be connected as close to VOUT pin and VSS pin to obtain stable phase compensation. Values required for the phase compensation are as the table below. For a stable power input, please connect an bias capacitor (CBIAS ) of 1.0F between the V BIAS pin and the VSS pin. Also, please connect an input capacitor (CIN) of 1.0F between the VIN pin and the VSS pin. In order to ensure the stable phase compensation while avoiding run-out of values, please use the capacitor (CBIAS, CIN, CL ) which does not depend on bias or temperature too much. The table below shows recommended values of CBIAS, CIN, CL. SETTING VOLTAGE 0.7V1.8V BIAS CAPACITOR CBIAS CBIAS=1.0F INPUT CAPACITOR CIN CIN=1.0F OUTPUT CAPACITOR CL CL=4.7F Recommended Values of CBIAS, CIN, CL 11/33 XC6601 Series OPERATIONAL EXPLANATION (Continued) <Soft-Start Function> With the XC6601, the inrush current from VIN to VOUT for charging CL at start-up can be reduced and makes the VIN stable. The soft-start time is optimized to 240s (TYP.) at VOUT=1.2V internally. Soft-start time is defined as the VOUT reaches 90% of VOUT(E) from the time when CE H threshold 0.75V is input to the CE pin.

Figure3: Timing chart at IC start-up <CL High Speed Auto-Discharge> XC6601 series can quickly discharge the electric charge at the output capacitor (CL) when a low signal to the EN pin which enables a whole IC circuit put into OFF state, is inputted via the N-channel transistor located between the VOUT pin and the VSS pin. When the IC is disabled, electric charge at the output capacitor (CL) is quickly discharged so that it could avoids malfunction. At that time, CL discharge resistance is depended on a bias voltage. Discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance (R) and the output capacitor (CL). By setting time constant of a CL auto-discharge resistance value [R] and an output capacitor value (CL) as (=C x R), the output voltage after discharge via the N channel transistor is calculated by the following formulas. V = VOUT x e -t/, or =ln VOUT(E) / V V : Output voltage after discharge, VOUT(E) : Output voltage, t: Discharge time, : CL auto-discharge resistance RxOutput capacitor (CL) value C <Current Limit, Short-Circuit Protection> The XC6601 series' fold-back circuit operates as an output current limiter and a short protection of the output pin. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. When the output pin is shorted to the VSS level, current flows about 80mA. <Thermal Shutdown Circuit (TSD) > When the junction temperature of the built-in driver transistor reaches the temperature limit level (150 TYP.), the thermal shutdown circuit operates and the driver transistor will be set to OFF. The IC resumes its operation when the thermal shutdown function is released and the IC's operation is automatically restored because the junction temperature drops to the level of the thermal shutdown release temperature (125 TYP.). 12/33 XC6601 Series OPERATIONAL EXPLANATION (Continued) <Under Voltage Lock Out (UVLO) > When the VBIAS pin voltage drops below 2.0V (TYP.) or VIN pin voltage drops below 0.4V (TYP.), the output driver transistor is forced OFF by UVLO function to prevent false output caused by unstable operation of the internal circuitry. When the VBIAS pin voltage rise at 2.2V (TYP.) or the VIN pin voltage rises at 0.4V (TYP.), the UVLO function is released. The driver transistor is turned in the ON state and start to operate voltage regulation. <CE Pin> The IC internal circuitry can be shutdown via the signal from the CE pin with the XC6601 series. In shutdown mode, output at the VOUT pin will be pulled down to the VSS level via R1 & R2. However, as for the XC6601 series, the CL auto-discharge resistor is connected in parallel to R1 and R2 while the power supply is applied to the VIN pin. Therefore, time until the VOUT pin reaches the VSS level becomes short. The CE pin of XC6601A has pull-down circuitry so that CE input current increase during IC operation. The CE pin of XC6601B does not have pull-down circuitry so that logic is not fixed when the CE pin is open. If the CE pin voltage is taken from VBIAS pin or VSS pin then logic is fixed and the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry when medium voltage is input. NOTE ON USE 1. 2. 3. 4. 5. 6. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be exceeded. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current. Please keep the resistance low between VBIAS and VSS wiring or VIN and VSS wiring in particular. Please wire the bias capacitor (CBIAS), input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible. Capacitance values of these capacitors (CBIAS, CIN, CL) are decreased by the influences of bias voltage and ambient temperature. Care shall be taken for capacitor selection to ensure stability of phase compensation from the point of ESR influence. In case of the output capacitor more than CL=22F is used, ringing of input current occurs when rising time. VIN and CE should be applied at least 10s after the bias voltage VBIAS reaches the requested voltage. If VIN and CE are applied within 10s, inrush current like 1A may occurs. 13/33 XC6601 Series TEST CIRCUITS Circuit Circuit Circuit * For the timing chart, please refer to page 12 <Soft-Start
