The AP7387 series is a wide input voltage range (60V), low quiescent current, high PSRR linear regulator able to drive 150mA output current. The AP7387 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 current-limit circuit for current protection, short-circuit protection, and thermal shutdown protection. The AP7387 has 3.0V, 3.3V, 3.6V, and 5V fixed output voltage versions, and is available in the SOT23, SOT25, SOT89, and U-DFN2020-6 packages.
