i am using LM7805 whose output voltage 5V and Output Current 1A i have used this to feed 5V supply for my application Circuit and my application circuit draw 125mA current , even tho 125mA current is less than the 1000 mA my LM7805 is slightly heated and application circuit not behave like its original functionality so what should be the probable issue that my power supply circuit is having do you think and please let me know and sorry for my poor english !!! thank you !!!
Problem got solved and this issue is because of microcontroller oscillator frequency and after scaling down this frequency problem got solved !!!
