LM123/LM323A/LM323

3-Amp, 5-Volt Positive Regulator

An overall worst case specification for the combined effects

of input voltage, load currents, ambient temperature, and

power dissipation ensure that the LM123 will perform satis-

factorily as a system element.

General Description

The LM123 is a three-terminal positive regulator with a pre-

set 5V output and a load driving capability of 3 amps. New

circuit design and processing techniques are used to provide

the high output current without sacrificing the regulation

characteristics of lower current devices.

For applications requiring other voltages, see LM150 series

adjustable regulator data sheet.

Operation is guaranteed over the junction temperature range

−55˚C to +150˚C for LM123, −40˚C to +125˚C for LM323A,

and 0˚C to +125˚C for LM323. A hermetic TO-3 package is

used for high reliability and low thermal resistance.

The LM323A offers improved precision over the standard

LM323. Parameters with tightened specifications include

output voltage tolerance, line regulation, and load regulation.

The 3 amp regulator is virtually blowout proof. Current limit-

ing, power limiting, and thermal shutdown provide the same

high level of reliability obtained with these techniques in the

LM109 1 amp regulator.

Features

n Guaranteed 1% initial accuracy (A version)

n 3 amp output current

No external components are required for operation of the

LM123. If the device is more than 4 inches from the filter ca-

pacitor, however, a 1 µF solid tantalum capacitor should be

used on the input. A 0.1 µF or larger capacitor may be used

on the output to reduce load transient spikes created by fast

switching digital logic, or to swamp out stray load capaci-

tance.

n Internal current and thermal limiting

n 0.01Ω typical output impedance

n 7.5V minimum input voltage

n 30W power dissipation

n P⁺Product Enhancement tested
