1. Specifications over the temperature range are guaranteed by design, characterization, and correlation with statistical process con-
trols.
2. Not including the current into internal resistance divider.
3. For fixed 3.3V and 5.0V output voltage version. The adjustable output voltage is guaranteed by reference voltage accuracy.
