HIGH RIPPLE-REJECTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR

The S-1112 S-1122 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. Compared with the voltage Regulators using the conventional CMOS process, 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.
