HIGH RIPPLE-REJECTION AND LOW DROPOUT
CMOS VOLTAGE REGULATOR
Rev.6.1_00
The S-1112/1122 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.
Small SNT-6A(H) (S-1112 Series only) and SOT-23-5 packages realize high-density mounting. In SOT-23-5,
the lineup includes the S-1112 and S-1122 Series, which differ in pin configuration.
