STMicroelectronics LM723
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.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 circuit provides internal current limiting. Provisions are made for adjustable current limiting and remote shutdown. DIP-14 Table 1.
