I'm going to use MIC5205 voltage regulator.
According to the datasheet and many sites and discussions I must use tantalum capacitors for the output. This LDO is unstable with ceramic capacitors (low-ESR caps in general). So I'm pretty aware of that.
But I'm not sure if I can use ceramic capacitors for bypassing in my circuit.
Here it's C26 that concerns me (that is just a sample, there are more ICs that are powered from "+3V3AN" rail). It is ceramic cap and I'm not sure if it will or will not cause a instability in my LDO.
I would assume it depends on the distance between LDO and that ceramic cap.
If this hypothesis is correct I have no idea what distance would be sufficient.
Unfortunately that would deteriorate line regulation.
