Please contact each Web shop for details such as availability of online samples.

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 capacitance 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 in a channel.
