Hi, Yes I was going from the datasheet and was wondering whether the ripple would affect the operation of the MCU.
Yes, that's why I asked the question I did.
This principal applies to hardwarew and software: don't optimize unless you have to.
Most linear regulators like the TPS series have such low ripple, you don't need to over complicate the decoupling solution. I think you'll find other aspects of your design are more critical than the 10mV of ripple from the regulator.'
Explain more about how the rest of your circuit works and maybe the suggestions so far might make more sense.
