... DESCRIPTION The S1F78B20 is a positive voltage CMOS regulator IC. This IC provides the low output noise, high-speed load transient response, high-load stability, and high accuracy mechanisms, ensuring 50µA, which is lower than the conventional consumption current. The output voltage is fixed in the IC, and its allowable range is between 1.8 to 4.0V based on the laser trimming technique ...
