The S-1132 Series is a positive voltage regulator with a low dropout voltage (LDO), high output voltage accuracy, and low current consumption (300 mA output current) developed based on CMOS technology. A 0.1 µF small ceramic capacitor can 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 of the 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 0.1 µF small ceramic capacitor. Also, the low current consumption makes the S-1132 series ideal for mobile devices.
