I've asked about this several other places, but no one seems to know the answer.
I would like to limit a speed controlled 12vdc fan to 9v max. The caveat being that anything below 9v be passed at the same voltage in-and-out, so a simple resistor wont do. Will a dropout voltage regulator correctly perform this function? Something like this? http://www.jameco.com/1/1/34873-ld1...drop-positive-fixed-voltage-regulator-9v.html
Or is a more complex circuit required?
Thanks,
Tony
