High Voltage Regulator Using Ic 723 Has Output Voltage. Ic 723 has two sections. 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.
Minimum output for floating regulators. Output voltage is not adjustable these limitations can be overcomes in ic723. The figure shown below is a positive voltage regulator with an ic 723.
Given below is the circuit diagram of switching voltage regulator using lm 2575.
7 volts is the reference starting voltage. This ic is known for its high efficiency and will clearly replace all 3 terminal linear voltage regulators. They made regulated power supplies using the 723 with outputs from 0 5 amps to 50 amps and voltages from 5 to 250 vdc yes 250vdc using the 723 ic. A constant current source a zener diode and a reference amplifier producing a constant voltage of about 7 volts at vref end.
