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 140µA quiescent current are ideal for
battery-powered system appliances. The APL5603 regu-
lators are stable with a 2.2µF 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.
