LM7805 - 5V Positive Voltage Regulator M30 The diameter of 4 largeLM7805 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
