General Description
The APL5301/2 series are micropower, low noise, low dropout linear regulators, which operate from 3V to 6V input voltage and deliver up to 300mA. Typical dropout voltage is only 260mV at 300mA loading. Designed for use in battery-powered system, the low 50uA quiescent current makes it an ideal choice. Design with an internal P-channel MOSFET pass transistor, the APL5301/2 maintain a low supply current, independent of the load current and dropout voltage.
Other features include reverse current protection, ther- mal-shutdown protection, current limit protection to ensure specified output current and controlled shortcircuit current. The APL5301/2 regulators come in a miniature SOP-8, SOT-23, SOT-23-5, SOT-89 and SOT-89-5 packages.
