HIGH RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR

S-1132 Series

The S-1132 Series is a positive voltage regulator with a low dropout voltage, high output voltage accuracy, and low current consumption (300 mA output current) developed based on CMOS technology. A 0.1 μF small ceramic capacitorcan be used. It operates with low current consumption of 20 μA typ. A built-in Output current protector prevents the load current

from exceeding the current capacitance ofthe output transistor.

Compared with the conventional 300 mA output current CMOS voltage regulators, high-density mounting is realized by using the super-small SNT-6A(H) package and a 0.1μF small ceramic capacitor. Also, the low current consumption makes the S-1132 series ideal for mobile devices.
