Adjustable 0 to 30 Volt Power Supply Project with LM317, where LM317 is a three-pin positive voltage regulator IC capable of supplying 3 amps within the output voltage range of 0 volts to 32 volts. It is extremely easy to use.
By using transistor 2N3055 (Q1), we have amplified the output current of the LM317 IC, which was 1.5 amps, and now we can have a maximum output current of 3 amps from this power supply.
How to use the Adjustable 2-30 Volt Power Supply Project with LM317
In the INPUT section, you should connect a 24-volt, 3-ampere transformer, and in the Q1 section, solder the 2N3055 transistor onto the board with a heatsink. The reason for placing it on a heatsink is to prevent the transistor from overheating when drawing current from the project. If it exceeds the temperature limit, it could lead to damage, and the heatsink helps to prevent this.
According to the circuit diagram that we constructed ourselves, there is an additional capacitor present, but we decided not to include it as it was not necessary. In the PCB that you are obtaining, this capacitor is not included, so there is no need to solder it.
In the OUTPUT section, you can adjust the voltage from 1 to 32 volts using a potentiometer. However, the output current is not adjustable. If you need to regulate the current as well, you can use a different power supply project that allows for both voltage and current adjustment.
