Project – LM7805 / L7805CV 5V Positive Voltage Regulator

LM7805 is one of the most commonly used Positive Regulator in Electronic circuits to lower down the voltage from the higher input voltage and it provides a regulated output of +5V with 2% regulation. This regulator has a ~2.5V linear drop-out. That means it must get at least +7V to get a clean +5V out. It dissipates the excess voltage in the form of heat, so you need to use a heat sink along with it to make sure it is working properly. There is a constant ‘quiescent’ current draw of 6mA. It has 3 terminals in the TO-220 package and it can handle up to 1A current. It is commonly used in Regulated power supply, as a current limiter in certain applications, constant 5V supply in many microcontrollers, sensors, and electronic appliances, etc. If you want a negative -5V Voltage Regulator, check out LM7905 IC.
