Hi uncle Sam, :) The regulator my be far away from the 9V input if you put another 10uF to 100uF closed to the regulator input. Then all your problems dissapears. Does the input supply voltage will be AC, single phase rectified or a DC with anti-foul reversal protection? cheers, Vasile cheers, Vasile -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
