I am using the Bosch BMP280 pressure sensor and the FGPMMOPA6H GPS chip together on a PCB. I am using the reference designs from Adafruit's breakout boards for each chip (found via the product links: BMP280, Ultimate GPS). Both breakout boards use the MIC5225-3.3V regulator, but have slightly different support circuitry.
Since these are going on the same board, I only need to use one voltage regulator for my 3.3V rail. From what I gather from Adafruit's documentation, the enable pin for the BMP280 is always high to keep that sensor on, while the enable pin for the GPS can be switched off to conserve power when the sensor is not needed. Is this correct? Why does the GPS also need a ferrite bead but the pressure sensor does not? Can I keep the ferrite bead in place without it affecting my other loads on the 3.3V rail (such as my ESP32)?
