I'm working on a new Xmega design I'll be running off a 5V supply, so I figured I'd put a 3.3V regulator by the CPU to provide its Vcc. All the parts I'm finding, though, require ceramic Cout caps with ESRs within a specified range, and I'm finding it very difficult to find caps that even specify their ESR, let alone have it in the proper range. This isn't a parameter that Digikey or Mouser let you filter by. Can anyone save me some digging and tell me what regulators and caps they've used in similar situations? Thanks.
