Hello.
I am designing a dual rail power supply based on linear regulators, but my transformer gives me 28V-0-28V, which with a rectifier gives me +-39V. But both regulators(one positive and one negative) accepts max +35V/-35V.
Does anyone have any suggestions on how to easy drop 5V from each rail?
The transformer can't be re-wind.
I'm i right in thinking that a MOSFET could be used referenced to a certain voltage?
