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