General Description
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, SOP-8, and DFN3x3-
8 packages.

Note 1: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020C for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
Note 2: For other voltage versions please contact ANPEC for details.
ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and
advise customers to obtain the latest version of relevant information to verify before placing orders.

Note 4: At elevated temperatures, device power dissipation must be derated based on package thermal resistance and heatsink
values. The junction-to-ambient thermal resistance is measured on a PC board mounting with the device soldered down to
minimum copper area. If power dissipation causes the junction temperature to exceed specified limits, the device will go into
thermal shutdown.
Note 5: The maximum allowable power dissipation at any T
