Where to use LM723 IC?
LM723 is an adjustable voltage regulator IC used for shunt regulator, current regulator, and temperature controller. It can able to provide a higher range of output voltage and current up to 10A by simply adding a series pass transistor with it, with having a wider range of operating temperature so the IC able to withstand for long. Also able to use as either linear or switching type regulator. But this IC is specially designed for series regulator application.
How to use LM723 IC?
To use this IC for the different range of required output voltage, you can proceed with various circuits available in LM723 datasheet with having your needed output range. For getting an output voltage range from 2v to 7v you can use the circuit below, which is a Basic Voltage Regulator circuit using LM723 voltage regulator IC.
Features
Excessive output current of 150mA without external pass transistor.
Better Input supply voltage of maximum 40v.
Provide adjustable output from 3v to 37v.
Used in making linear or switching regulator.
Able to provide 10A of output current with use of external pass transistor.
Used for various operation like positive supply, negative supply, series, shunt, and floating.
