LM7808 Description
LM7808 is a positive voltage regulator IC that provides fixed output of 8V DC. The IC is available in TO-220 package and it is produced by many electronic components manufacturers. It is the IC of LM78xx series LM78xx series contains many other fixed voltage ICs like LM7805, LM7806, LM7809, LM7810, LM7812, LM7815 & LM7824. One of the main advantage of these voltage regulators is that no matter if the input voltage is fluctuating they will provide fixed voltage at the output but the input voltage should not be less than the minimum required voltage of the ICs. The Input voltage in any condition must be 2V to 3V higher than the output voltage.
To get stable 8V output from LM7808 as discussed above it is suggested that the input voltage must be at least 2 to 3V higher than the output voltage. The IC is a DC device so the input voltage must be DC. Additionally to get 1.5A at the output the input current should be at least 2A.
