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 currentprotection,
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.
