how to make voltage regulator using transistor

how to make a voltage regulator using a transistor:

Today we are going to learn how to make a DC regulator. it’s a very simple project. We need only an NPN transistor. here we use TTC 5200 transistor. and we need one 100k variable. we can control 6 voltage to 50 voltage. it can supply 2/3 ampers. normally we make a DC fan for using battery but we can’t control the motor. because the market can’t find out this. for this cause I make for myself. and I am trying to tell you to make this dc voltage regulator for your dc fan ( car fan). 

 

here in this diagram, we can see how to make the diagram. Let’s go to watch a video for making this project. how to make a voltage regulator using the transistor.

 

we also can control our dc light according to our needs. and also we can use this circuit for battery charging. for charging, we just need to use a voltage meter for knowing the voltage according to our battery. here in this diagram we also can use any NPN transistor. let’s see how to make a voltage regulator using a transistor.
