AP7381
WIDE INPUT VOLTAGE RANGE, 150mA ULDO REGULATOR Description Pin Assignments The AP7381 series is a positive voltage regulator IC. (Top View) The AP7381 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. NEW PRODUCT GND 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. 3 VIN 2 GND 1 VOUT SOT89 (Option 2) The AP7381 has 3.3V, 5V fixed voltage version. (Top View) The AP7381 is available in space-saving SOT89 (Option 2) and TO92
(Ammo Packing) packages. Features
