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