SNVS317A – FEBRUARY 2005 – REVISED MARCH 2013
LM723JAN Voltage Regulator
Check for Samples: LM723JAN
•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 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 is also useful in a wide range of other
applications such as a shunt regulator, a current
regulator or a temperature controller.
NOTE: Pin 5 connected to case.
