General Description
The APL5156 is a low ground current linear regulator,
which operates with input voltage from 6.5V to 25V and
delivers output current up to 150mA. Typical dropout volt-
age is only 1.9V at 150mA loading. This combination of
the high voltage and the low ground current makes the
APL5156 ideal for USB and portable devices, using 2-
cell or 3-cell Li-Ion battery inputs.
The APL5156 is stable with aluminum, tantalum, and
ceramic capacitors. It requires a 2.2µF or greater capaci-
tor for stability.
The APL5156 has many protection functions, including
over-temperature, current-limit, reverse battery, and
reverse leakage protections which prevent the device from
thermal over-load, current over-load, reverse connection
of the battery and output current reversing to the VIN.
The APL5156 regulator is available in miniature SOT-23-
5, SOT-89, and SOP-8P packages.

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).
