AP7387

WIDE INPUT VOLTAGE RANGE, 150mA ULDO REGULATOR

Description

The

DIODES™ 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

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, 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, SOT89R

and U-DFN2020-6 (Type C) packages.
