AP7387 WIDE INPUT VOLTAGE RANGE, 150mA ULDO REGULATOR Description Pin Assignments The DIODES AP7387 series is a wide input voltage range (60V), low quiescent current, high PSRR linear regulator able to drive (Top View) (Top View) 150mA output current. VIN 3 VOUT 3 The AP7387 features a very fast line/load transient response against rapid input-voltage and load-current changes. The IC consists of a 2 voltage reference, an error amplifier, a current-limit circuit for current- VIN protection, short-circuit, and thermal-shutdown protection. 1 2 1 GND The AP7387 has 3.0V, 3.3V, 3.6V, and 5V fixed output voltage GND VOUT versions, and is available in the SOT23, SOT25, SOT89, and SOT23 SOT89 U-DFN2020-6 (Type C) packages.
