Low Dropout 600mA Fixed Voltage Linear Regulator

The APL5603 is a low-power and low dropout linear regu-

lators which operates from 2.9V to 6V input voltage and

delivers up to 600mA output current. Typical dropout volt-

age is only 220mV (typical) at 600mA output. The APL5603

regulators with low 140

µA quiescent current are ideal for

battery-powered system appliances. The APL5603 regu-

lators are stable with a 2.2

µF ceramic capacitor. The fea-

tures of current-limit, short-circuit current-limit, and over-

temperature protections can prevent the device against

currnet overload and over-temperature. The APL5603

regulators are availabe in SOT-23-5, TSOT-23-5, SOP-8,

and DFN3x3-8 packages.
