Typicals are measured at 25 C.
Values given here are preliminary estimates prior to completing characterization.
Most customers are expected to find that auto-wakeup from stop2 or stop3 can be used instead of the higher current wait
mode.
Values given under the following conditions: low range operation (RANGE = 0), low power mode (HGO = 0).
