GSENSOR_3V3 voltage drop

I have some questions regarding the GSENSOR_3V3 line:
Under normal conditions I measured 2.8V. In suspend, the voltage drops to
2.4V. I thought the the line would carry 3.3V when powered on and ~0V in
suspend. Why isn't that the case?
How much current should I be able to get from this line? I connected the
three-axis magnetometer HMC5843 which works fine when the phone is powered on.
It even takes measurements in suspend, but then the voltage drops down to
1.76V when a measurement takes place (every second for 4ms).
Can someone explain how this is supposed to work?
