The AP7387Q series is a wide input voltage range (60V), low quiescent current, high PSRR linear regulator able to driver 150mA output current.

The AP7387Q features a very fast line/load transient response against the rapid input voltage and load current changes. The IC consists of a voltage reference, an error amplifier, a resistor network for setting output voltage, a current limit circuit for current protection, short-circuit and thermal shutdown protection.

The AP7387Q has 3.0V, 3.3V, 3.6V, and 5V fixed output voltage versions, and is available in the SOT89 and U-DFN2020-6 (SWP) (Type UXC) packages.
