The IC 7805 provides circuit
designers with an easy way to regulate DC voltages to 5v. Encapsulated
in a single chip/package (IC), the 7805 is a positive voltage DC regulator that has only 3 terminals. They are: Input voltage, Ground, Output Voltage.

Although the 7805 were primarily
designed for a fixed-voltage output (5V), it is indeed possible to use
external components in order to obtain DC output voltages of: 5V, 6V,
8V, 9V, 10V, 12V, 15V, 18V, 20V, 24V. Note that the input voltage must,
of course, be greater that the required output voltage, so that it can
be regulated downwards
