Ultra low drop BICMOS voltage regulator

Feature summary

■ 1.5A Guaranteed output current

■ Ultra low dropout voltage (200mV typ. @ 1.5A

load, 40mV typ. @300mA load)

■ Very low quiescent current (1mA typ. @ 1.5A

DPAK

PPAK

load, 1µA max @ 25°C in off mode)

■ Logic-controlled electronic shutdown

■ Current and thermal internal limit

■

1.5% Output voltage tolerance @ 25°C

■ Fixed and ADJ output voltages: 1.22V, 1.8V,

DFN8 (4x4 mm)

2.5V, 3.3V, ADJ. (*see order code)

■ Temperature range: -40 to 125°C

■ Fast dynamic response to line and load

Description

changes

The LD39150 is a fast ultra low drop linear

regulator which operates from 2.5V to 6V input

supply.

■ Stable with ceramic capacitor (see paragraph

7.1, 7.2, 7.3)

■ Available in PPAK, DPAK and DFN8 (4x4mm)

A wide range of output options are available. The

low drop voltage, low noise, and ultra low

quiescent current make it suitable for low voltage

microprocessor and memory applications. The

device is developed on a BiCMOS process which

allows low quiescent current operation

Typical application

■ Microprocessor power supply

■ DSPs power supply

■ Post regulators for switching suppliers

■ High efficiency linear regulator

independently of output load current.
