7812 Voltage Regulator IC

Voltage regulators are very common in electronic circuits. They provide a constant output voltage for a varied input voltage. In our case, the 7812 IC is an iconic regulator IC that finds its application in most of the projects. The name 7812 signifies two meaning, ?78? means that it is a positive voltage regulator and ?12? means that it provides 12V as output. So our 7812 will provide a +12V output voltage.
