HIGH RIPPLE-REJECTION LOW DROPOUT
CMOS VOLTAGE REGULATOR
Rev.4.0
_00
The S-1165 Series is a positive voltage regulator with a low dropout voltage, high output voltage accuracy, 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 protector prevents the load current from exceeding the current capacitance of the output transistor.
An ON/OFF circuit ensures a long battery life, and a small SOT-23-5 package realizes high-density mounting.
Features
1.5 V to 5.5 V, selectable in 0.1 V steps.
