That should mean something like this:
I need a simple circuit to regulate the voltage around 12 V while enabling at least ~10 W for some load I have (0,833 A)
My idea was to use a simple zener diode, a capacitor and a voltage regulator for the 12 V output
What do you think? for R1 I thought about 5-30 ohm, for Zn1 30 Vbkd and C1 ~ 0,00001 F.
Do you have any comments about the layout or values?
Thanks in advance!
