Jim: I thought of putting a few diodes but a 3V drop at 7Amp maximum is 21W, too much waste in the worst cases scenario.
Claire: Understood - just pointing out the awkward limit. Look forward to seeing the new devices!
By the way - I posted this on a separate forum ('Other products') but is it possible to get exact coordinates for the .1" holes in the regulators? The outline dimensions and mounting hole spacing is not enough to build a PCB that allows direct soldering of these guys on top.
