精密稳压器 PRECISION VOLTAGE REGULATOR
DESCRIPTION
This monolithic voltage regulator is designed for use with either positive or negative supplies as a series, shunt, switching, or floating regulator with currents up to 150mA. Higher current requirements may be accommodated through the use of external NPN or PNP power transistors. This device consists of a temperature compensated
reference amplifier, error amplifier, power series pass transistor, current limit, and remote shutdown circuitry.
FEATURES
