For many years I've powered my projects with LM1806 or similar regulator, usually running it through a full wave bridge so you can use just about any off the shelf wallwart.
I'm now looking at a project where the power input available is 24VAC, and this presses the LM1806 a bit hard and creates a lot of heat. So I'm looking for
a better solution.
I need 250MA @ 3.3v
I'd like it to be somewhat cost effective (IE no $10 solutions). Anyone have any suggestions?
Maybe I can use the LM1806 just used in a different configuration?
