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.
