Voltage regulators are very common in electronic circuits. They provide a constant output voltage for a varied input voltage. The name 7815 signifies two meanings, “78” means that it is a positive voltage regulator and “15” means that it provides 15V as output. So our 7815 will provide a +15V output voltage. The output current of this IC can go up to 1.5A. But the IC suffers from heavy heat loss, hence a Heat sink is recommended for projects that consume more current. For example, if the input voltage is 20V, and you are consuming 1A, then (20-5) * 1 = 15W. This 15 Watts will be dissipated as heat.
