Irfz44n Voltage Regulator Circuit Diagram. Variable voltage power supply circuit using irfz44n mosfet. Simple voltage regulator using irfz44n and 5ok potentiometer regulate dc volt adjustable 1 2 to 39v diy dc power supply fb page.
Jun 17 2019 hello friends today in this video i have shown how to make a simple voltage regulator using a irfz44 mosfet. Irfz44n is an n channel mosfet so the drain and source pins will be left open when there is no voltage applied to the gate pin. This power supply can provide current upto o 5 ampere.
If it is required to be switched with arduino then a simple drive circuit using a transistor will work to provide the required gate voltage to trigger the mosfet.
You can adjust the output voltage by varying the pot. The irfz44n on the other hand requires a gate driver circuit if the. Its input voltage supplied from the rectifier circuit. But remember to install good heat sink for the.
