AP7380

WIDE INPUT VOLTAGE RANGE, 150mA ULDO REGULATOR

Description

The AP7380 series is a positive voltage regulator IC.

The AP7380 has features of wide input voltage range, high accuracy,

low dropout voltage, current limit and ultra-low quiescent current

which make it ideal for use in various USB and portable devices and

instrument application.

The IC consists of a voltage reference, an error amplifier, a resistor

network for setting output voltage, a current limit circuit for current

protection, and a chip enable circuit.

The AP7380 is available in 1.8V, 3.0V, 3.3V, 3.6V, 4.15V, 4.4V and

5.0V fixed output voltage versions.

The AP7380 is available in space-saving SOT25 and SOT89 (Option

2) packages.
