Feature summary

■ 3A Guaranteed output current

■ Ultra low dropout voltage (200mV typ. @ 3A

load, 40mV typ. @600mA load)

■ Very low quiescent current (1.2mA typ. @ 3A

load, 1µA max @ 25°C in off mode)

■ Logic-controlled electronic shutdown

■ Current and thermal internal limit

DPAK

PPAK

■

1.5% Output voltage tolerance @ 25°C

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

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

■ Temperature range: -40 to 125°C

■ Fast dynamic response to line and load

Description

changes

The LD39300 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 and DPAK

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 switchin suppliers

■ High efficiency linear regulator

independently of output load current.
