Voltage Regulator Using Ic 723. For inconsistent voltage regulation an lm317 ic voltage regulator is used which we have discussed in the previous article. Line regulation set il as 1 ma by varying 10k pot vary the vin input voltage and note the corresponding changes in load voltages.
The maximum supply voltage is 40 v and the line and load regulations are each specified as 0 01. Vref drives the non inverting input of the operational amplifier. The voltage regulator using lm340 ic is the most used voltage regulator ic.
14 high voltage regulator using ic 723 circuit diagram.
Vref drives the non inverting input of the operational amplifier. Ic 723 as a low voltage regulator the lm723 is the adjustable voltage regulator ic designed for series regulator application with a current output of 150ma without external pass transistor. Continuous voltage from v to v 40v. Being a linear regulator the ic 723 needs an input supply that should be at least 3 v higher than the desired output voltage and the maximum difference between the input and the output voltage should never be allowed to exceed 37 v.
