 How to Make Adjustable Voltage Regulator Using Mosfets | Adjustable Voltage Controller

1. You can adjust the Output voltage from 1.5 volt to 35 volt provided the input voltage is greater then output voltage by at least 2 to 3 volt

2. In the circuit the purpose of the Diode is to protect from short circuits.

a) Diode D1 protects from internal short circuits &

b) Diode D2 protects from external short circuits

Things You Need

***Part List***

1.LM317

2. 5K Trimpot

3. 1N4001 - 2

4.Heat Sink

5.Male Header

6. 330 ohm resistor

7. 10uf/25volt Capacitor

8. 0.1uF Ceramic Capacitor

9.PCB Board

10 Soldering Items

Circuit Diagram & Finished Images

The Circuit diagram for the voltage regulator is shown in the first image. Construct the circuit according to the circuit diagram.

Note: Don't Forget to connect an Heat Sink to the IC

To adjust the Output voltage fuse the trimmer pot. The Voltage can be adjusted from 1.5 volt to 35 vol & also note the input voltage should always be greater then the output voltage. In the circuit we have used two Diodes. The purpose of the diode is to protect from short circuits.
