HIGH RIPPLE-REJECTION LOW DROPOUT

SOFT-START FUNCTION CMOS VOLTAGE REGULATOR

Rev.2.1

_02

The S-1137 Series, developed using the CMOS technology, is a positive voltage regulator IC which has the low dropout

voltage, the high-accuracy output voltage and the soft-start function (300 mA output current).

A 1.0

F

small ceramic capacitor can be used. It operates with low current consumption of 45

A

typ.

The overcurrent protection circuit prevents the load current from exceeding the current capacity of the output transistor.

The ON / OFF circuit ensures longer battery life.

Compared to the conventional CMOS technology regulator ICs, various capacitors including small ceramic capacitors can be

used for this IC.

Furthermore, small SOT-89-5, SOT-23-5, and SNT-6A(H) packages realize high-density mounting.
