Pin 7805 Circuit Diagram. For example if the input voltage is 12v and you are consuming 1a then 12 5 1 7w. This is a typical application circuit of the 7805 ic.
I have attached an image of 7805 ic to describe its pin configuration. 7805 voltage regulator a member of 78xx series of fixed linear voltage regulators used to maintain such fluctuations is a popular voltage regulator integrated circuit ic. An unregulated voltage is applied to this input pin for regulation.
Each pin and its function can be discussed below.
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. It s generally used with ac to dc power supply. This voltage regulator includes three pins namely input pin ground pin and output pin. 7805 voltage regulator pin diagram.
