In the MPL3115A2 altimeter datasheet there is: "A second 100 nF capacitor is used to bypass the internal regulator". Please explain is that meas that the internal regulator can be disabled? And also please explain in what cases should someone bypass the internal regulator when the VCC must be stabilised anyways? In my case I use lm317 adjusted to 3,3V. Thank you.
