Voltage and Current Regulated Power Supply
Related Page - LM723 Power Supply
Here is a Simple Voltage and Current Regulated Power Supply using the LM723 IC. With the Values Shown, It is Adjustable from 3 to 30 Volts and 0 to 3 Amps. This circuit does NOT have Output SHORT CIRCUIT Protection, So a 3 Amp Fuse on the Output would be a Good Idea. Ideally you will put an Amp-Meter, Where is says “M” on the PCB. If you Don’t, you Must put a Wire Jumper across there.
The LM723/LM723C is a voltage regulator designed primarily for series regulator applications. By itself, it will supply output currents up to 150 mA; but external transistors can be added to provide any desired load current. The circuit features extremely low standby current drain, and provision is made for either linear or foldback current limiting.
