S-1131 Series

HIGH RIPPLE-REJECTION AND LOW DROPOUT

MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR

Rev.4.1

_01

The S-1131 Series is a positive voltage regulator with a low dropout voltage, high-accuracy output voltage, and

low current consumption developed based on CMOS technology.

A built-in low on-resistance transistor provides a low dropout voltage and large output current, and a built-in

overcurrent protection circuit prevents the load current from exceeding the current capacitance of the output

transistor. An ON/OFF circuit ensures a long battery life, and small SOT-89-3, SOT-89-5 and 6-Pin HSON(A)

packages realize high-density mounting.
