5V to 24V DC Variable Regulator by 7805

Advertisements

The output voltage can be adjusted (varied) from 5v to 24v via a potentiometer connected to the common line of the regulator. The input voltage and heatsinking of the regulator must be sufficient for the output voltage and current. The output may not deliver more than 100mA @ 5v due to the heat produced by the regulator if the input voltage is say 24v - 36v. This is one of the disadvantages of a variable power supply if this design.
