High Voltage Regulator Using Ic 723 Circuit Diagram. A constant current source a zener diode and a reference amplifier producing a constant voltage of about 7 volts at vref end. 7 volts is the reference starting voltage.
Unregulated dc supply voltage at the input between 9 5v 40v. It has an ability to provide up to 150 ma of current to the load but this can be increased more than 10a by using power transistors. It can be used as both positive and negative voltage regulator.
A constant current source a zener diode and a reference amplifier producing a constant voltage of about 7 volts at vref end.
Disadvantages of fixed voltage regulator. Output voltage is not adjustable these limitations can be overcomes in ic723. The 723 voltage regulator is commonly used for series voltage regulator applications. The load must be able to drain at least the supply current of the 723 circuit without exhibiting a voltage higher than the desired output voltage.
