load, 40mV typ. @600mA load)

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

load, 1碌A(chǔ) max @ 25擄C in off mode)

Logic-controlled electronic shutdown

Current and thermal internal limit

PPAK

DPAK

鹵

1.5% Output voltage tolerance @ 25擄C

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

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

Temperature range: -40 to 125擄C

Fast dynamic response to line and load

changes

Stable with ceramic capacitor (see paragraph

7.1, 7.2, 7.3)

Available in PPAK and DPAK

Description

The LD39300 is a fast ultra low drop linear

regulator which operates from 2.5V to 6V input

supply.

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

independently of output load current.

Typical application

鈻?/div>

Microprocessor power supply

DSPs power supply

Post regulators for switchin suppliers

High efficiency linear regulator
