APL5155

High Input Voltage, Low Quiescent Current, 150mA LDO Regulator

Features

General Description

• Wide Input Voltage Range: 5.4V to 25V

The APL5155 is a low ground current linear regulator,

• Ultra Low Ground Current: 10µA

which operates with input voltage from 5.4V to 25V and

• High Output Accuracy: ±2.5%

delivers output current up to 150mA. Typical dropout volt-

• Excellent Load/Line Transient

age is only 750mV at 150mA loading. This combination

• Low Dropout Voltage: 750mV @ 150mA

of the high voltage and the low ground current makes the

APL5155 ideal for USB and portable devices, using 2-

•

Fixed Output Voltages for 5V/3.3V or Adjustable

cell or 3-cell Li-Ion battery inputs.

Voltage

The APL5155 is stable with aluminum, tantalum, and

• Built-In Current-Limit Protection

ceramic capacitors. It requires a 1µF or greater capacitor

• Built-In Over-Temperature Protection

for stability.

• Zero Shutdown Current

The APL5155 has many protection functions, including

• Internal Soft-Start Function

over-temperature, current-limit and short circuit current

• POR Scheme to Prevent VOUT Spike

limit protections, which prevent the device from thermal

• SOT-23-5, SOT-89, and SOP-8P Packages

• Lead Free and Green Devices Available

(RoHS Compliant)

over-load and current over-load.

The APL5155 regulator is available in miniature SOT-23-

5, SOT-89, and SOP-8P packages.
