Power supply with LM723 Electrical Engineering Stack Exchange
LM723 IC is also a voltage regulator but it can generate a variable voltage which can be adjusted in a range of 3V to 37V. It is basically used in the series regulator application. Although it offers a 150mA output current. But we can get an excessive current of up to 10A for driving the load by connecting a bypass transistor externally.

This LM723 0-30V adjustable power supply circuit diagram provides output voltage between 0 and 30 volts at a maximum current of 1 Amp. Because the standard LM723 circuit minimum output voltage is 2 volts, to the ground of the integrated circuit terminal (pin 7) is applied - 4.7 volts, using Zener diode D4. R8 resistor limits the maximum output.

LM723 Power Supply Schematic. To reduce the effect of wire resistance, connect the output voltage detector and the - side of the board as close as possible to the output terminal as shown in the circuit diagram above. Also, the wire (about 6 cm) from the + side switch to the output terminal doubles, resulting in a loss of 2.5 to 3 mV at 3.5 A.
30V Regulated Power Supply LM723 YouSpice
a) why the zener is shorted to ground, and the effect of this (I have seen it either greatly limit the range of Vo, or make the whole thing unstable) b) what the role of the LM723 is in this circuit. I understand that it is responsible for varying the voltage (and regulating it), how is it accomplishing this?
