"LM7806 is a voltage regulator IC of LM78xx IC series. It provides fixed 6V DC positive output with 1A to 1.5A output current. The IC contains many built in features like over heat shutdown function, overload shutdown, short circuit protection / shutdown which make it reliable and ideal to use in commercial equipment.
The maximum input the IC can handle is 35V DC and minimum input to achieve stable 6V at the output should be 8V because the IC requires 2V above than its output to provide stable 6V output. A heatsink is a must to use with this IC because it dissipates heat during operation.
