LM123/LM323A/LM323-N 3-Amp, 5-Volt Positive Regulator

Check for Samples: LM123, LM323-N, LM323A

The 3 amp regulator is virtually blowout proof.

FEATURES

Current limiting, power limiting, and thermal shutdown

provide the same high level of reliability obtained with

these techniques in the LM109 1 amp regulator.

30W Power Dissipation

No external components are required for operation of

the LM123. If the device is more than 4 inches from

the filter capacitor, 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 capacitance.

DESCRIPTION

An overall worst case specification for the combined

effects of input voltage, load currents, ambient

temperature, and power dissipation ensure that the

The LM123 is a three-terminal positive regulator with

a preset 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.

LM123 will perform satisfactorily as

element.

a system

For applications requiring other voltages, see LM150

series adjustable regulator data sheet.

The LM323A offers improved precision over the

standard LM323-N. Parameters with tightened

specifications include output voltage tolerance, line

regulation, and load regulation.

Operation is specified 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-N. A

hermetic TO-3 package is used for high reliability and

low thermal resistance.
