linear regulator with two microproces-

sor compatible control functions and

protection circuitry included on chip.

The composite NPN-PNP output pass

transistor assures a lower dropout volt-

age (1V @ 200mA) without requiring

excessive supply current (2.5mA).

moves out of regulation. The

signal is valid down to V_OUT= 1V.

■ Low Dropout Voltage

(1V @ 150mA)

The CS8120 design optimizes supply

rejection by switching the internal

bandgap reference from the supply

input to the regulator output as soon as

the nominal output voltage is achieved.

Additional on chip filtering enhances

rejection of high frequency transients

on all external leads.

■ Low Quiescent Current

(2.5mA @ I_OUT= 150mA)

The CS8120Õs two logic control func-

tions make this regulator well suited to

applications requiring microprocessor-
