DESCRIPTION
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.
The 3 amp regulator is virtually blowout proof.
Current limiting, power limiting, and thermal shutdown
provide the same high level of reliability obtained with
these techniques in the LM109 1 amp regulator.
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.
An overall worst case specification for the combined
effects of input voltage, load currents, ambient
temperature, and power dissipation ensure that the
LM123 will perform satisfactorily as a system
element.
For applications requiring other voltages, see LM150
series adjustable regulator data sheet.
