HIGH RIPPLE-REJECTION
LOW DROPOUT CMOS VOLTAGE REGULATOR
Rev.3.1
_02
The S-T111 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 capacity of the output
transistor. An ON/OFF circuit ensures a long battery life. Compared with the voltage regulators using the
conventional CMOS technology, a larger variety of capacitors are available, including small ceramic capacitors.
A small SOT-23-5 package realizes high-density mounting.
