lm723 variable power supply circuit design
The LM723 voltage regulator is a versatile device that can be configured for a wide range of applications, making it ideal for use in a variable power supply circuit. The circuit typically consists of the LM723 integrated circuit, a few passive components, and a heat sink to manage thermal dissipation.
The output voltage is adjustable through the use of a potentiometer connected to the feedback pin of the LM723. This allows for fine-tuning of the output voltage within the specified range of 8 to 30 volts. The output current capability of 3 amperes makes it suitable for powering various electronic devices and circuits.
To achieve the low output ripple voltage of 0.5 mV, the circuit may include additional filtering components, such as capacitors and inductors, which smooth the output signal. This is crucial for sensitive applications where voltage stability is paramount.
Protection features are integral to the design. Short circuit protection is typically implemented using a current sensing resistor and a comparator circuit that can disconnect the load in the event of a fault. Overload protection can be achieved by incorporating a thermal shutdown feature, which automatically reduces the output current if the temperature of the LM723 exceeds safe operating limits.
Overall, this LM723 variable power supply circuit design is a robust solution for providing adjustable power with essential protective features, making it suitable for both hobbyist and professional applications in electronics.This LM723 variable power supply circuit design is a very simple variable power supply that will provide an output voltage between 8 and 30 volt at a maximum output current of 3 ampere.
