7805 Ic Pin Diagram. The name 7805 signifies two meaning 78 means that it is a positive voltage regulator and 05 means that it provides 5v as output. Save this picture for reference.
The output current of this ic can go up to 1 5a. 7805 ic provides 5 volts regulated power supply with provisions to add a heat sink. Hence a 7805 would regulate 5v and 7806 would regulate 6v and so on.
The xx in 78xx indicates the output voltage it provides.
Down below is a typical application circuit of the lm7805 ic which lm7805 work as 5v voltage regulator. Save this picture for reference. Output voltage range v max 5 2v v min 4 8v. The gnd of both input and out are given to pin 2.
