The S-13D1 Series, developed by using the CMOS technology, is a 2-channel positive voltage regulator IC which has low

dropout voltage, high accuracy output voltage and low current consumption.

A 0.22

μF small ceramic capacitor can be used, and the S-13D1 Series includes a load current protection circuit that

prevents the output current from exceeding the current capacity of the output transistor and a thermal shutdown circuit that

prevents damage due to overheating. Also, C / F type in the S-13D1 Series has a built-in delay function that sets the

difference of rising time between channels.
