LM7809 Description:
LM7809 is a fixed positive voltage regulator IC. The IC provides fixed 9V ouput with 1A to 1.5A. To achieve a fixed and stable output voltage of 9V and 1.5 ampere the input voltage should be 11V and 2 ampere. If the input voltage will be lower than 11V then the IC will not provide fixed 9V because it requires 2V above from its actual output voltage to provide a stable output. The maximum input voltage limit is 35V DC. A suitable heatsink is must to use with the IC because all the voltage difference will convert into heat in the IC. Moreover the IC also contains many built in features like over heat shutdown and short circuit protection that makes it reliable to use in many commercial applications and also in educational electronics projects.
