5.333 Volt for Roland Filters

I think using a variable three-legged regulator such as the 317T would 
be easier (less parts) and better (stiffer, less noise -- you can add extra 
caps and diodes to a 317 to get them really quiet).  I am sure a 317 can 
handle more current than anything required by a TB-303.

OTOH, I think bad engineering is greatly responsible for the 303's 
sound.  So maybe, you want a worse voltage regulator :)
