I assume you mean 220VAC to DC. Buying an adapter will be safer and less work.looking for a mini compact Ic regulator which could output 3.3v,5.5v from input 220v.Any suggestions
What you showed is not isolated from the power line. Only use it if your project is in a plastic box with no way to touch any part on the board.is there is an alternate rather than a transformer
