LM123/LM223
LM323
THREE-TERMINAL 3A-5V POSITIVE VOLTAGE REGULATORS
. OUTPUT CURRENT : 3A
. INTERNAL CURRENT AND THERMAL LIMI-
TING
. TYPICAL OUPUT IMPEDANCE : 0.01Ω
. MINIMUM INPUT VOLTAGE : 7.5V
. POWER DISSIPATION : 30W
DESCRIPTION
The LM123, LM223, LM323 are three-terminal posi-
tive 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 ob-
tained with these techniques in the LM209, 1A regu-
lator.
An overall worst case specification for the combined
effects of input voltage, load current, ambient tem-
perature, and power dissipation ensure that the
LM123, LM223, LM323 will perform satisfactorily as
a system element.
