SERIES

5A LOW DROP POSITIVE VOLTAGE

REGULATOR ADJUSTABLE AND FIXED

TYPICAL DROPOUT 1.3V (AT 5A)

THREE TERMINAL ADJUSTABLE OR FIXED

OUTPUT VOLTAGE 1.5, 1.8V, 2.5V, 2.85V,

3.3V, 3.6V, 5V, 8V, 9V, 12V.

GUARANTEED OUTPUT CURRENT UP TO

OUPUT TOLERANCE ± 1% AT 25°C AND

D PAK

INTERNAL POWER AND THERMAL LIMIT

WIDE OPERATING TEMPERATURE RANGE

-40°C TO 125°C

TO-220

PACKAGE AVAILABLE: TO-220, D PAK,

D PAK/A

PINOUT COMPATIBILITY WITH STANDARD

ADJUSTABLE VREG

A 2.85V output version is suitable for SCSI-2

active termination. Unlike PNP regulators, where

a part of the output current is wasted as quiescent

current, the LD1084 quiescent current flows into

the load, so increase efficiency. Only a 10µF

minimum capacitor is need for stability.

The device is supplied in TO-220, D PAK and

D PAK/A. On chip trimming allows the regulator to

reach a very tight output voltage tolerance, within

±1% at 25°C.

DESCRIPTION

The LD1084 is a LOW DROP Voltage Regulator

able to provide up to 5A of Output Current.

Dropout is guaranteed at a maximum of 1.5V at

the maximum output current, decreasing at lower

loads. The LD1084 is pin to pin compatible with

the older 3-terminal adjustable regulators, but has

better performances in term of drop and output

tolerance.
