APL5155 datasheet



The APL5155 is a low ground current linear regulator,which operates with input voltage from 5.4V to 25V and delivers output current up to 150mA. Typical dropout volt age is only 750mV at 150mA loading. This combination of the high voltage and the low ground current makes the APL5155 ideal for USB and portable devices, using 2-cell or 3-cell Li-Ion battery inputs. The device is stable with aluminum, tantalum, and ceramic capacitors. It requires a 1mF or greater capacitor for stability.

The IC has many protection functions, including over-temperature, current-limit and short circuit current limit protections, which prevent the device from thermal over-load and current over-load.
