Contact Sales

Description

The AP7375 series is a wide input voltage range (45V), low quiescent current (2.1μA), low-dropout linear regulator (LDO) able to provide 300mA load current. The AP7375 family of LDOs 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, 3.6V, and 5.0V fixed output voltage versions, and is available in the SOT23, SOT25, SOT89, and U-DFN2020-6 (SWP) (Type UXC) packages.
