I'm trying to design a custom board that will include the FGPMMOPA6H GPS.
Looking at the Adafruit integration of this GPS, I can see a ferrite bead on the output of the LDO (MIC5225-3.3). See below:
I agree with the use of an LDO to get a clean power supply for the GPS, but I don't know how to choose a "good" ferrite bead on its output.
I'm not very familiar with the use of ferrite beads, so a little help would be highly appreciated!
