Description
The LM323 are three-terminal positive voltage
regulators with a preset 5 V output and a load
driving capability of 3 A. New circuit design and
processing techniques are used to provide the
high output current without sacrificing the
regulation characteristics of lower current devices.
The 3 A regulator is virtually blowout proof.
Current limiting, power limiting and thermal shut-
down provide the same high level of reliability
obtained with these techniques in the LM209, 1 A
regulator. An overall worst case specification for
the combined effects of input voltage, load
current, ambient temperature, and power
dissipation ensure that the LM323 will perform
satisfactorily as a system element.
