General Description
The APL5308/9 series are micropower, low dropout linear regulators, which operate from 2.7V to 6V input voltage and deliver up to 300mA. Typical dropout voltage is only 400mV at 300mA loading. Designed for use in battery-powered system, the low 60mA quiescent current makes it an ideal choice. Design with an internal Pchannel MOSFET pass transistor, theAPL5308/9 maintain a low supply current, independent of the load current and dropout voltage. Other features include thermal-shutdown protection current limit protection to ensure specified output current and controlled short-circuit current. The APL5308/9 regulators come in a miniature SOT-23-3, SOT-23-5, and SOT-89 packages.
