LM1084

5A Low Dropout Positive Regulators

General Description

Features

n Available in 3.3V, 5.0V, 12V and Adjustable Versions

n Current Limiting and Thermal Protection

n Output Current

The LM1084 is a series of low dropout voltage positive

regulators with a maximum dropout of 1.5V at 5A of load

current. It has the same pin-out as National Semiconductor’s

industry standard LM317.

n Industrial Temperature Range

n Line Regulation

n Load Regulation

−40˚C to 125˚C

0.015% (typical)

0.1% (typical)

The LM1084 is available in an adjustable version, which can

set the output voltage with only two external resistors. It is

also available in three fixed voltages: 3.3V, 5.0V and 12.0V.

The fixed versions intergrate the adjust resistors.

Applications

The LM1084 circuit includes a zener trimmed bandgap ref-

erence, current limiting and thermal shutdown.

n Post Regulator for Switching DC/DC Conveter

n High Efficiency Linear Regulators

n Battery Charger

The LM1084 series is available in TO-220 and TO-263 pack-

ages. Refer to the LM1085 for the 3A version, and the

LM1086 for the 1.5A version.
