Decent 24 volt Pic power supply

Thanks for all the comments and suggestions. I surely could run the two linears back to back like that and get away with it. Overall, a good simple switcher would still be the best bet as far as heat and effeciency. I break down and build some protos when I get time and come up with one for my library.

Again, Thanks to all and have a Merry Christmas.

I had a client project that ran on 24 volts AC and needed a good 12 volt supply for a camera, then 5 for a PIC. I used a switching regulator from National with a minimum number of parts to drop to 12 VDC. As I recall, the regulator didn't even get warm to the touch with 400 mA of current draw!
