Pin 3 (Output Pin): The Output pin is the regulated 5 volts DC. Pin 2 (Ground): Ground pin establishes the ground for the regulator. Pin 1 (Input Pin): The Input pin is the pin that accepts the incoming DC voltage, which the voltage regulator will eventually regulate down to 5 volts. The LM7805, like most other regulators, is a three-pin IC.

LM78XX: Voltage regulators that output positive voltage, “XX”=voltage output. The other series of regulators, the LM79XX, is the series that outputs negative voltage. The “78” part is just the convention that the chip makers use to denote the series of regulators that output positive voltage.

A LM7805 ends with “05” thus, it outputs 5 volts. An easy way to remember the voltage output by a LM78XX series of voltage regulators is the last two digits of the number.
