DESCRIPTION
The LM123, LM223, LM323 are 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
shut-down provide the same high level of reliability
obtained with 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
TO-220
TO-3
dissipation ensure that the LM123, LM223, LM323
will perform satisfactorily as a system element.
