APL5308-15A/B Datasheet – 300 mA, Fixed Voltage Regulator

Part Number: APL5308-15A/B

Function: 4.5 V, low IQ, Low Dropout 300 mA, Fixed Voltage Regulator

Manufacturer: Anpec Electronics


APL5308-15A/B datasheet



The APL5308 / APL5309 series are micropower, low dropout linear regulators, which operate from 2.7V to 6V input voltage and del i ver up to 300mA. Typical dropout voltage is only 400mV at 300mA loading. Designed for use in battery-powered system, the low 60mA qui escent current makes it an ideal choice.

Design with an internal P-channel MOSFET pass transistor, the APL5308/9 maintain a low supply current, independent of the load current and dropout voltage. Other features include thermal-shutdown  p rotection current limit protection to ensure specified output current and controlled short-circuit current . The APL5308 / APL5309 regulators come in a miniature SOT-23-3, SOT-23-5, and SOT-89 packages.
