Here is a suggestion for a 300ma/15VDC regulator. The ideas behind it come from Walt Jung's articles and somehow at the starting point from the flea reg designed on the PFM boards. The layout is not for PCB making but for stripboard soldering.
Obviously the TL071-TL081 are a big step down from the opamps used in the Jung's but they insure almost unconditional stability. A ne5534 (compensated with 22pf) could be also used but decoupling becomes critical; as shown by Mooly here: diyAudio Forums - Low cost regulator in between Jung and Flea . The TL071 are still "ok" compared to three pins regs, as shown by ALW here: diyAudio Forums - Reducing noise in voltage regulators
I received many useful comments on Diyaudio (mainly from Mooly, Onvinyl, Jan Didden and AndrewT) but if someone here had something to add, I'd be delighted to hear it
