General Description
The APL5320/A is a P-channel low dropout linear regula-
tor which needs only one input voltage from 2.5 to 6V, and
delivers current up to 300mA to set output voltage. It also
can work with low ESR ceramic capacitors and is ideal for
using in the battery-powered applications such as note-
book computers and cellular phones. Typical dropout volt-
age is only 290mV at 300mA loading.
The APL5320/A provides several versions of fixed output
voltages ranging from 1.2 to 3.7V with step 100mV and
2.85V, 4.75V. Current-limit with current foldback and ther-
mal shutdown functions protects the device against cur-
rent over-loads and over-temperature. The APL5320/A is
available in SOT-23-5, TSOT-23-5, SOT-23-3, SC-70-5,
VTDFN1.2x1.6-4, SC-82-4, TDFN1.5x1.5-6 and TDFN 1.

Note : 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-020D 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).
