Hello,
I am trying to find a schematic for a -5V PSU that can be derived from +5V or +9V input voltage. Current consumption is about 300-500mA. My transformer has not gor a center tap. I would like to use a +9v from a jack wall
I am going to use this to feed some opamps
The simplest the better, I would prever the use of linear regulators.
Thank you
