HIGH RIPPLE-REJECTION
LOW DROPOUT CMOS VOLTAGE REGULATOR
S-1165 Series
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.
