Hello friends, today in this video i have shown how to make a simple voltage regulator using a irfz44 mosfet. But remember to install good heat-sink for the mosfet.

The IRFZ44 is not intended to be used in linear mode like this! It is designed for switching applications where it is hard on or hard off. Your application could result in excessive power dissipation an destroy the Mosfet.

This deceptively simple circuit is extremely elegant for many reasons. The mosfet is being inserted in series with the positive lead. Then the pot. serves as a voltage divider to pick off the desired gate voltage. So the mosfet is only turned on enough to create the required voltage drop to obtain whatever output voltage is desired. Since a mosfet requires virtually almost zero gate current, a very high resistance pot. can be used. Also, if you want to use a higher input voltage, just use a mosfet that can stand more voltage. I wanted to go from 48 volts down to around 14 volts to operate a 7809 regulator. I had an IRF 830 mosfet kicking around in the junkpile. It can do 500 volts at 4.5 amps. I set up my experiment using a 1 megohm pot. Works perfectly! Once you find out the values of the divider, then you can substitute in fixed resistors instead of the pot. In my case I ended up with 470k from +48v to the mosfet gate, and from there the other leg of the divider is 270k to minus side of 48 volt supply. 1/4 watt resistors are fine because the power dissipated is only a few microwatts. Those values yield an output voltage of 14.2 volts. That output sags very little under load too. This circuit works great for knocking down 48 volts to 14 volts to serve as the input for the 7809 regulator. 7809 regulator can only stand 35 volts max on its input. This circuit is very useful because it is so simple and yet so elegant. Mosfets need nearly zero gate current. Also at first glance this circuit looks as if it may need some amount of output load resistance to make the gate positive with respect to the source. But to my utter surprise, it does not need that. The open source lead has the 14 volts on it with no load resistance. That was a very pleasant surprise which still doesn't make too much sense, but seeing is believing. This circuit is quite stable under load. Much more stable than I would have thought. Thanks for posting this! It makes possible taking 48 volts and getting 9 volts regulated using only 4 parts! The 14 volts from the mosfet is the unregulated input to the 7809 9 volt regulator. Then that regulator holds 9 volts rock steady up to a 1 amp. load. At that full 9 volt current, the mosfet voltage sags only down to 11.8 volts or so. Quite amazing.

This is not a voltage regulator and the whole thing will burn if you try to load it and you can't get stable voltage out of it anyway. If you want to make a linear voltage regulator you could just use lm317t which is less expensive than a mosfet and is actually a regulator

An LM317 would have to be paired with a PNP bipolar junction transistor to handle the current and wattage that the MOSFET can. It would be more expensive, but, it would indeed be a true variable regulated power supply. No matter what, a large heat sink, or a small one with a cooling fan is necessary, if you want to pass several amps with a big difference in voltage between the source and the output voltage. An LM317 only handles about an amp or so, where the IRF44 can handle 10 amps or more, as long as it doesn't dissipate more than 94 watts.

@@vincentrobinette1507 it's meaningless to use a mosfet anyway and the mosfet and lm317t both will handle pretty much the same current since their power dissipation is mostly limited by to-220 case which they both have the same. But at least lm317t will keep the same voltage with various loads and is also cheaper and original lm317t ic is nearly impossible to burn, even when it gets too hot it just limits the current and nothing really happens to it while mosfets are quite easy to break especially if the temprerature is high

This primitive circuit is rather an electronic load for testing power supplies or bstteries than a voltage regulator. Regulators need a feedback loop in order to keep the output voltage stable, independent of either line or load variations. This is missing here. Even the electronic loads need that feedback loop in order to draw stable current from (say) a battery under test, while its voltage drops under the discharging process. No feedback, no regulator. Just primitive voltage adjust circuit...

A good heat sink is a good idea if it is to drive a heavy load. The amperage X the voltage across the drain/source junction will tell how many watts the transistor will dissipate. The regulation isn't very tight, because as the supply voltage drops, the output of the 'regulator' will drop by the same percentage. There's also some voltage drop due to the gain of the transistor.

Is not really a voltage regulator, is just like an high power variable resistor. As the mosfet works like a resistance, higher currents will drop the voltage so is not stable at all. Also at lower voltages and higher currents, the disipated heat will be high and the mosfet can blow up. If you want a real voltage regulator, take a look to switching IC regulator or buck converters (they has much more stability and also much less losses as heat).

Yes, I agree with you and this only works well if Vin is a fixed stable voltage to start with however true voltage regulators are a total pain in the ass. My problem is trying to find regulators and or circuits online which are immune to drop out, many things I am trying to power need a stable 12 volt supply, I live semi off-grid with a 12volt battery bank, easy you would say, what is your problem? trouble is 12.2 volts is a totally empty battery my system voltage hardly ever dips below 12.6 volts and can be as high as 14.7 volts when on a charge, trying to get something which will take the varying voltage and give out a flat 12 volts is like trying to find a unicorn. Many Chinese parts which claim to do the job do not match the details given on spec sheets and finding something that will supply about 5 Amps is virtually impossible, they can put men on the moon but this seems too much of a challenge for the semiconductor industry. And I know about low drop out regulators but they usually only supply a meagre 1 amp.

True, but it is tighter than a rheostat would be, and it's much easier to mount the MOSFET on a heat sink, than to find the 94 watt rheostat that would be the alternative. The transistor can be purchased for less than $1.00 US, and the potentiometer for about the same. I use this circuit quite often, when I just need a quick and dirty way to vary the voltage to a device or circuit board, to test the permissible voltage swing.

Is the max amperage depending on the input and the max Drain output of 41amp of IRFZ44 Transistor..? is there any potentiometer/variable resistor can hold a 10amp current.? Thank you.

The power MOSFET turns the potentiometer into a power resistor. But it needs a big heatsink.

A potentiometer big enough to handle 10 amps is called a Rheostat. They are huge, almost the size of a variac. The output is NOT regulated. The IRFZ44 MOSFET can handle up to 94 watts of dissipation if mounted on a big heat sink. At 10 amps, the maximum difference between the supply voltage and output voltage is 9.4 volts.

all your load is going through your 10K pot thin tracks, which is not going to last long as soon as you will hook up any sufficient load to it. Not a good idea.
