HIGH RIPPLE-REJECTION SOFT-START FUNCTION

CMOS VOLTAGE REGULATOR

Rev.1.3

_02

The S-1335 Series, developed by using the CMOS technology, is a positive voltage regulator IC of 150 mA output current,

which has low dropout voltage, high-accuracy output voltage and soft-start function.

The rising time of output voltage immediately after power-on or after the ON / OFF pin is set to ON is adjustable. A 1.0

F

small ceramic capacitor can be used. It operates with low current consumption of 36

A

typ. Furthermore the overcurrent

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

SOT-23-5, SC-82AB and super small HSNT-4 (1010) packages realize high-density mounting.
