20 Amp Variable Power Supply using LM317 Electronics Area

exceptionally easy to use and require only 2 resistors to set the output voltage. Careful circuit design has resulted in outstanding load and line regulation, comparable to many commercial power supplies. The LM138 family is supplied in a standard 3-lead transistor package. A unique feature of the LM138 family is time-dependent current limiting. The current limit circuitry allows peak currents...
The complete circuit of this Variable Power Supply is shown below, Follow the Schematics and solder you components accordingly. As shown in schematics the variable voltage of 1.5 to 24V is mapped to 0-4.5V by using potential divider circuit, since our Arduino can only read voltages from 0-5.

The LM317 is versatile in its applications, including uses in programmable output regulation and local on-card regulation. Or, by connecting a fixed resistor between the ADJUST and OUTPUT terminals, the LM317 …

  • This LM317 circuit is capable to provide variable DC power supply with output of 1A and can be adjusted up to 30V. The circuit consists of a low-side resistor and high-side resistor connected in series forming a resistive voltage divider which is a passive linear circuit used to produce an output voltage which is a fraction of its input voltage.
  • This is a basic universal variable Power Supply voltage regulator circuit using an LM317, 3-terminal regulator in a TO-220package. The Universal Power Supply output voltage can be set to anywhere in the range 1.5V to 30V by selecting two resistances.
