SNVS765C – JUNE 1999 – REVISED APRIL 2013
LM723/LM723C Voltage Regulator
Check for Samples: LM723, LM723C
•2 150 mA Output Current Without External Pass
• Output Currents in Excess of 10A Possible by
Adding External Transistors
• Input Voltage 40V Max
• Output Voltage Adjustable from 2V to 37V
• Can be Used as Either a Linear or a Switching
The LM723/LM723C is a voltage regulator designed
primarily for series regulator applications. By itself, it
will supply output currents up to 150 mA; but external
transistors can be added to provide any desired load
current. The circuit features extremely low standby
current drain, and provision is made for either linear
or foldback current limiting.
The LM723/LM723C is also useful in a wide range of
other applications such as a shunt regulator, a
current regulator or a temperature controller.
The LM723C is identical to the LM723 except that the
LM723C has its performance ensured over a 0°C to
+70°C temperature range, instead of −55°C to
