voltage regulator circuit diagram

voltage regulator circuit diagram:

This is the voltage regulator circuit diagram for 12 voltage. this type of circuit can make strong amperes. we usually use 7912 for 12 voltage. this is for the negative voltage. here, I used one 12-volt Ziner diode. this ziner diode regulates the voltage. we get the voltage according to the ziner diode.
