This is another versatile and flexible chip. I could design current sources, voltage to current transmitters, level translation and many more. You can think of applications beyond the Power Electronics Scope with this.
“The circuit provides internal current limiting. When the output current exceeds 150mA an external NPN or PNP pass element may be used. Provisions are made for adjustable current limiting and remote shutdown.”
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
Some Specs –
Input voltage up to 40V, Output voltage adjustable from 2 to 37V, Output current to 150mA without external pass transistor and Adjustable current limiting.
