    Andy, I would place a 10uF ceramic cap across the processor after the 100 Ohm resistor. I would also replace the 100 Ohm with a 10 Ohm. I have to ask what are you doing with the remaining pins on the processor? Also, what other circuits are you powering from the LDO? I am assuming the regulator is somewhere on the left of the schematic?
