Hey, [Newbie question] I need to convert 24vac to ~5vac for ultimate rectification/regulation to +5vdc. I'm looking at transformers to step down to 5vac from 24vac. Most of what I'm finding take 115vac input. Would I be foolish to use a transformer rated at 115vac input to 24vac output, but input my 24vac instead of the 115vac and expect ~5vac out (i.e. 24v*(24v/115v) = ~5.00v)? My goal is to rectify the ~5vac (resulting in ~7vdc) and then regulate that to +5vdc using an LM7805. TIA. -Mitch PS I tried a solid state approach using a TL783 to go from rectified 24vac (34 vdc) directly to 5vdc, but producing 50-70ma the TL783 heated a very hefty heat sink to the point that it was too hot to touch in ~15 minutes.
