Gah. I just blew (or just noticed that I blew) the 440mA fuse in my DMM. Mouser carries the part but it costs US$22! Grainger carries it for US$8.65
I was able to stop at Radio Shack on the way home and get some 10W power resistors for testing the power supply. I’m having no problems getting about 490mA out of it, which is more than enough for its intended application. Unfortunately the resistors get fairly hot when sinking that much current, so I can’t run them for too long.
Still, things are good with that… I guess I’ll finish part footprint validation and get on with laying out the board.
