In the datasheet, they show a feedback pin bias current only at 25C and VIN = 3.0V. How does this FB pin bias current vary across temperature and input voltage? I did not see any graphs showing these variations.

Rustin,

The FB pin current increases with respect to temp. The current can be as high as 700nA at 125C. There should be no change with respect to input voltage. Hope this helps.
