this is the pcb im using. i have provided room for large 100uF tantalums, which made the whole pcb much bigger. i shouldnt have done that as the tiny 10uf ceramic ones are adequate. also, the thermal reliefs in the copper pour increase the path the current has to travel, which calls for more parasitic loops and spikes. the placemet of the output capacitor is also very critical.. anyway, enough of self-criticism. im going to redesign this w/o those huge tantalum pads in parallel.
