The AP7375Q series consists of wide input voltage range (45V), low quiescent current (2.1µA), low-dropout linear regulators (LDOs) able to provide 300mA load current. The AP7375Q LDO family offers an EN pin to enable and disable the LDO output. The EN pin can take an input voltage of 45V.

The device provides a very fast response against line voltage transient and load current transient, and ensures no overshoot voltage occurs during startup and short-circuit recovery. It also features integrated short-circuit and thermal-shutdown protection.

The AP7375Q has 1.8V, 3.0V, 3.3V, and 5.0V fixed output voltage versions, and is available in the SOT89, SO-8EP, SOT25, and U-DFN2020-6 (SWP) (Type UXC) packages.
