The L7805 is fixed 5v power regulator a series of 3 positive terminal available in TO-220, it has fixed output voltage making it useful in a wide range of application such as powering up you Arduino, Raspberry Pi, Modules and other staff you want to use. These regulator can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. On each type employs internal current limiting, thermal shutdown and safe are protection making it essentially indestructible. if using high output current heat sink should be place on the regulator, the device can deliver over 1A output current. Although designed primarily as fixed voltage regulator , these L7805 can be used with external components to obtain adjustable voltage and currents. see the schematic below how to wire this device.

To wire the L7805 fixed voltage regulator into your projects see the schematics below.
