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 voltage 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 2cell or 3-cell Li-Ion battery inputs.
The APL5156 is stable with aluminum, tantalum, and
ceramic capacitors. It requires a 2.2µF or greater capacitor 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-235, SOT-89, and SOP-8P packages.
