Hello,
what would be the course of action to get 15V from a 16-18V DC source? The source is some kind of an adapter and it is not reliable.
L7815 requires at least 17.5V if I understand correctly?
I tried putting smoothing capacitor and a HF filter, but I still get ~16-17VDC.
Would it be ok just to put a 15V zener diode and a suitable series resistor (suitable as in terms of wattage) ?
Thanks.
