FEATURES

DESCRIPTION

The SC1714 is a 3-terminal negative voltage regulator

with an output voltage rated at 3.3V below the positive

supply voltage. Designed to be an improved plug in

replacement for the BA714, it offers a low typical

supply current of 12µA, a high output current sinking

capability of 5mA, and a low negative temperature

coefficient. It also features output overload protection.

The SC1714 is ideal as a power source for liquid

crystal displays.
