Hi, I think there is a way to convert a 7805 regulators to 9v using some diodes in the ground terminal. Is that true, and how is it accomplished?
So just an ordinary low power zener, it does not need to be a high power type?If you can accepts some voltage tolerance, use 3.9V zener diode in series with ground terminal. Bias current is almost constant, around 5 mA.
inside the 7805 the (load) current goes from INPUT to OUTPUT.I am going to draw something like 200-300mA
