You misconnected something- which is why you should also have a fuse and/or diode on the input power. Secondly, your LM7805 will run a bit hot because you are forcing it to drop ~7V... it has to dissipate that energy. You could use a zener/transistor circuit ahead of the LM7805 to drop the voltage, or use an LM7808 to approximately halve the 7V problem, which will let the LM7805 run cooler.Dear Friends,
I am using Atmega328P, input source of 12V10A with 7805 Voltage Regulator, when I connect the input source the regulator Capacitor got burnt.
Kindly advice, if we need to add 7812 voltage regulator before 7805?
