Hello,

I used very simple power supply for my circuit that used a micro-controller.


in my board exists 7812 for stabilization.
is it suitable fr micro?
If i use it, what problems may be occur?

thanks.
 

That will work if the micro operated on 12V. Since most operate on 5V and 12V would zap them, you could use a 7805 instead which gives a regulated +5V.
