DESCRIPTION

The LM123, LM223, LM323are three-terminal positive

voltage regulators with a preset 5V output and

a load driving capability of 3A. New circuit design

and processing techniques are used to provide the

high output current without sacrificing the regulation

characteristics of lower current devices.

The 3A regulator is virtually blowout proof.

Current limiting, power limiting and thermal shutdown

provide the same high level of reliability obtainedwith

these techniques in the LM209, 1A regulator.

An overall worst case specification for the combined

effects of input voltage, load current, ambient temperature,

and power dissipation ensure that the

LM123, LM223, LM323 will perform satisfactorily as

a system element.
