DescriptionThe LM723/LM723C is a voltage regulator designed primarily for series regulator applications. By itself, itTransistor will supply output currents up to 150 mA; but external  can be added to provide any desired load  current.Features 150 mA Output Current Without External Transistor 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 regulator
