LM723
High precision
voltage regulator
Features
■ Input
voltage up to 40 V ■ Output
voltage adjustable from 2 to 37 V ■ Positive or negative supply operation ■ Series, shunt, switching or floating operation ■ Output current to 150 mA without external pass
transistor ■ Adjustable current limiting
Description
The LM723 is a monolithic integrated programmable
voltage regulator, assembled in 14-lead dual in-line plastic package. The circuit provides internal current limiting. When the output current exceeds 150 mA an external NPN or PNP pass element may be used. Provisions are made for adjustable current limiting and remote shutdown.
