But using batteries in sensitive electronic circuits is not a good idea as batteries eventually drain out and loose their potential over time.Īlso, the voltage provided by batteries are typically 1.2V, 3.7V, 9V and 12V. One of the important sources of DC Supply are Batteries. The device may get damaged if there is any deviation from the fixed rate. A regulated power supply is very much essential for several electronic devices due to the semiconductor material employed in them have a fixed rate of current as well as voltage. In this tutorial, we will see about one of the most commonly used regulator IC’s, the 7805 Voltage Regulator IC. Important Points on 7805 Voltage Regulator IC.How to Get Constant DC Power Supply from AC?.Pin Diagram of 7805 Voltage Regulator IC.
