I have one toroidal transformer 2x12VAC @ 0.63A - 15VA, 7.5VA each winding.
I want to use one winding from the transformer and put it into a full wave bridge rectifier then I'll have 16.9 VDC without diodes losses. I thinck this voltage is good to work with the regulator 7812 ?
My questions are:
What happens with current, is still remains at 0.63A after regulation ?
How can I calculate the output current, because I need to build a circuit and it need only 150mA @ 12VDC
Please help !!
