7812 12V Voltage Regulator

Description

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.

The output current of this IC can go up to 1.5A. But, the IC suffers from heavy heat loss hence a Heatsink is recommended for projects that consume more current. For example, if the input voltage is 19V and you are consuming 1A, then (19-12) * 1 = 7W. This 7 Watts will be dissipated as heat.
