The power supply is a basic need for those who put their first step in electronics. Through this, we can test our homemade constructions as well as our circuits and appliances. But sometimes we need certain values of voltages to test your circuits such as 12V. So we make this circuit for a 12V power supply.
What is a 12V Power Supply?
12V power supply is a linear power supply that constantly provided the 12V at the output in the input voltage is 12V and above. This is a linear power supply so the LM7812 voltage regulator IC may get hot so uses a heat sink with it to protect it. The input voltage must be between 12V to 30V.
