Everything was worked properly with lm78L05 which has a 5v/100ma output,somtimes after 3/4 hours of continues working it get hot.
So to solve that i was suggested to use lm7805 which gives 5V/1amp output,when i connect pin1 of the lm7805 to the input means after D2 and D3 in my circuit and pin 3 to the output means +5V connections of the circuit,pin 2 to the circuit ground,after doing this it makes burn the microcontroller and mosfetQ1,and lm7805 still gives 5v output it doesnt effected by all this.
Which part cause the problem
