LM7805 5V Linear Voltage Regulator IC-Pack of 3

DESCRIPTION

Voltage regulators are very common in electronic circuits. They provide a constant output voltage for a varied input voltage. LM7805 5V Linear Voltage Regulator IC is an iconic regulator IC that finds its application in most of the projects. The name 7805 signifies two meaning, “78” means that it is a positive voltage regulator and “05” means that it provides 5V as output. So our 7805 will provide a +5V output voltage.

The output current of this IC can go up to 1A. 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 12V and you are consuming 1A, then (12-5) * 1 = 7W. This 7 Watts will be dissipated as heat.

to run this IC and getting regulated voltage, it just need two capacitors of vale 33uf and 0.1uf to get this IC working. The input capacitor 0.33uF is a ceramic capacitor that deals with input inductance problem and the output capacitor 0.1uF is also a ceramic capacitor that adds to the stability of the circuit. These capacitors should be placed close to the terminals for them
