HIGH RIPPLE REJECTION AND

LOW DROPOUT VOLTAGE REGULATOR

The S-1111/1121 series is a positive voltage regulator that

features low dropout voltage, high output voltage accuracy,

and low current consumption, and has been developed using

CMOS technology. Since a low on-resistance transistor is

incorporated, the dropout voltage is small, and a large output

current can be obtained. A built-in overcurrent protection cir-

cuit prevents the load current from exceeding the current

capacitance of the output transistor. Moreover, the battery

life can be extended by using the power-on/off circuit. Small

SOT-23-5 and 5-pin SON(A) packages realize high-density

mounting. The lineup includes the S-1111 and S-1121 se-

ries, which differ in pin configuration.
