Hello all, sorry for my poor english, it isn't my native language,
I have a problem, probably really simple, I have 2 circuits that I try to power up in parallel one of them take a tension between 9 and 12 volt and the other one take 4.5 volt, and I was wondering how I could do to use only one source, so I was thinking about putting the 2 circuits in parallel and use a zener diode to regulate the voltage of the circuit that take 4.5V but I am not sure about how I should put in place that circuits and how to use the zener diode to regulate the voltage.
Any help is welcome, thank you in advance.
