[sdiy] Power Supply

[Oscar Salas]

Hello,

I would like to power two circuits that work toguether , one of them needs +15V/0V/-15V and consumes 33 mA per rail. The other needs +15V/0V and consumes 57mA.

My questions are: Can I feed both circuits, with the same power supply, with a transformer that could feed those 90mA (33mA+57mA) of the positive rail or it would be better, to use two separate power supplies dedicated to each circuit? Its bad to make that a transformer work asymmetrically?



Thanks,

Oscar.
