supply current versus supply voltage for nRF52832 ?

[danmcb]

from the datasheet we see that this device can operate at 1.8V or 3V3 (or anything in between).

We can also check supply current on the mRF52DK which runs at 3V3.

How would we expect supply current to vary if our design operates at 1V8?

Are there any published graphs of current versus supply voltage? I could not find any.

Many thanks.

If you're using LDO mode, and not DCDC; the current draw is constant over the supply voltage.
