You could chain a +9 regulator between them, so that the +5 regulator only sees the ripple out of the +9. > It's all black magic to me.

What I read was that you do NOT want a ground plane under your switcher, as it would couple all that switching noise into the ground plane. I introduced the power planes at the final filter capacitor. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
