DESCRIPTION
The SC112 is a 150mA ultra low dropout linear
regulator with a built in CMOS/TTL logic level enable, designed specifically for battery powered applications where low quiescent current and low dropout are critical for battery longevity.
The SC112 uses a Semtech proprietary internal
PNP device for the pass element, providing a low dropout voltage of 130mV at a load of 60mA.
The output noise is reduced to 30µV (typical) by placing a very low leakage 10nF capacitor on pin 3 (noise bypass).
Each device contains a bandgap reference, error...
