General Description
The APL5101/2 are micro-power, ultra low dropout
linear regulator, which operate from 2V to 6V input
voltage and deliver up to 150mA. Typical dropout
voltage is only 200mV at 150mA loading. Designed
for use in battery-powered system, the low 4µA
quiescent current makes it an ideal choice. Design
with an internal P-channel MOSFET pass transistor,
the APL5101/2 maintain a low supply current,
independent of the load current and dropout voltage.
Other features include thermal-shutdown protection
and current limit protection to ensure specified
output current and controlled short-circuit current.
The APL5101/2 regulator come in a miniature SOT-23,
SOT-23-5 and SOT-89 packages.
