SUPER-SMALL PACKAGE 2-CIRCUIT BUILT-IN DELAY FUNCTION
HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR
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.
