High Voltage Regulator Using Ic 723. 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. The lm723 is the adjustable voltage regulator ic designed for series regulator application with a current output of 150ma without external pass transistor.
Lm723 voltage regulator features. Pulse voltage from v to v 50 ms 50v. Unregulated dc supply voltage at the input between 9 5v 40v.
The 723 voltage regulator is commonly used for series voltage regulator applications.
Output current is 150ma without an external pass transistor. The output voltage can be set to any desired positive voltage between 7 37 volts. Disadvantages of fixed voltage regulator. The figure shown below is a positive voltage regulator with an ic 723.
