LM123/LM323A/LM323
3-Amp, 5-Volt Positive Regulator
General 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 LM323A offers improved precision over the standard
LM323. Parameters with tightened specifications include
output voltage tolerance, line regulation, and load regulation.
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.
Operation is guaranteed over the junction temperature range
?55°C to +150°C for LM123, ?40°C to +125°C for LM323A,
and 0°C to +125°C for LM323. A hermetic TO-3 package is
used for high reliability and low thermal resistance.
Features
n Guaranteed 1% initial accuracy (A version)
n 3 amp output current
n Internal current and thermal limiting
n 0.01W typical output impedance
n 7.5V minimum input voltage
n 30W power dissipation
n P+ Product Enhancement tested
