Dc Variable Voltage Regulator Circuit Diagram

The lm117 series of adjustable 3 terminal positive voltage regulators are able to provide in excess of 0 5a over a 1 2v to 37v output range.

Dc variable voltage regulator circuit diagram. Which you can adjust output voltage in a wide range between 0v to 50v and a current at least 3a. Given below is the diagram of a 1 2 v to 25 volts adjustable voltage regulator circuit using lm117 ic. Generally electronic circuits using tubes or transistors require a source of d c. Also the important is the overload protection.

This regulator is 0 50v variable power supply circuit. In input out output adj adjust. They are very easy to handle and require only two external resistors to set the output voltage. The lm317 regulator terminals are.

This lm317 circuit is capable to provide variable dc power supply with an output of 1a and can be adjusted up to 30v. The lm317 is a 3 terminal positive voltage regulator with a 1 25 to 37 volts output voltage range. The battery voltage feeding the dimming circuit ranges anywhere from 12 9vdc up to as high as 19 2vdc and then is variable all the way down to 0vdc. Working of lm317 voltage regulator circuit.

The capacitor c1 used for the filtering of dc input voltage and further fed to the vin pin of the lm317 voltage regulator ic. I am working on a project involving the dimming circuit on an automobile and led s. A list of voltage regulator circuit with diagram includes adjustable linear variable boost and switching voltage regulators of 5v 6v 9v 12v and 25 vots. This voltage regulator circuit is very simple.

Since it will immediately cut off when a load short circuit. The lm317 circuit is shown in the below figure is a t y pical configuration of the lm317 voltage regulator circuit diagram including the decoupling capacitors. The adjustable pin is connected with the two external resistor and connected with the vout pin of the ic.
