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.
