If the MP3V5050V is operated on a 3 Volt button cell/battery, will the output voltage for the pressure measurement change/decrease as the battery voltage decreases?

1) If the MP3V5050V is operated on a 3 Volt button cell/battery, will the output voltage for the pressure measurement change/decrease as the battery voltage decreases?

 

2) Should I use a voltage regulator in my circuit for the supply voltage to the MP3V5050V?

 

I am trying to conserve the coin battery power so power efficiency is important. I know that a switching regulator in the correct configuration will most likely extract more energy from a dying battery than a linear regulator which will eventually drop out. I am not certain whether noise generated from the switching regulator affect the pressure measurement?

 

3) How sensitive is the MP3V5050V to switching noise?

 

4) Can you recommend a switching regulator or a linear regulator that might work? Thank you.
