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.
