You've probably done this but the supply rails to your more sensitive analogue circuitry should be better filtered and stablised, as per methods above, compared...
...in a potential divider?  Or maybe some 3.3v zeners

Hi,Can't you just divide the existing supply rail? Plenty of low voltage In. Amps around
