I've got a couple SCAMP modules I'd like to rack up. They need +/- input voltages which get regulated down via L791x/L781x.
Now I'd like to use a wall wart single ouput AC transformer to power the modules. In the past the schematic attached provided by PRR has always worked well used by itself, now I wonder if it can be combined with the regulators (with the voltages adapted for the application).
Stupid question probably, but I think I tried this once before and may have gotten sparks or smoke. Or voiced differently, is there a compelling reason not to do it like this, since technically the ground is derrived directly from one of the secondary connections.
Thanks!
