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.
