Being a latecomer in non-os DAC, I need to ask a few questions here..

I built my first TDA1545 DAC a while ago, check and re-check and re-recheck, and Im pretty sure I did not mess up my circuit. However, once I connected the power, the regulator IC gets hot and I dont think its normal. I guess I had voltage latch up problems here...
Question is, using the same regulator for digital and analogue supply will solve this problem? Or is there other methods? Did I just blew up my CS8412 IC?
Does anyone have a CONFIRMED working circuit for me to refer to? I got my schematics from diyparadise, I know its accurate, but I wanted to doublecheck.. There seems to be so many variations over the internet for this project
