AP7375

WIDE INPUT VOLTAGE RANGE, 300mA ULDO REGULATOR

Description

The

DIODES™ AP7375 series is a wide input voltage range (45V),

low quiescent current (2.1uA), low-dropout linear regulator (LDO) able

to provide 300mA load current. The AP7375 family LDO offers an EN

pin that takes an input voltage of 45V to enable and disable the LDO

output.

The device features very fast response times against line voltage

transient and load current transient, and ensures no overshoot

voltage during start-up and short-circuit recovery. It also features

integrated short-circuit and thermal shutdown protection.

The AP7375 has 1.8V, 3.0V, 3.3V, and 5.0V fixed output voltage

versions, and is available in the SOT23, SOT25, and SOT89

packages.
