Based on CMOS technology, Seiko Instruments’ S-13A1 Series is a positive voltage regulator with a low dropout voltage, high output voltage accuracy and low current consumption. Developed with a 2.2-uF small ceramic capacitor, the regulator uses a load current protection circuit preventing the output current from exceeding the current capacitance of the output transistor and a thermal shutdown circuit preventing damage due to overheating. The S-13A1 Series includes an inrush current limit circuit which limits the excess inrush current at power-on and at turn-on of the ON/OFF pin.
