(1) 100% of production is tested at TA = +85°C. Specifications over temperature range are ensured by design.
(2) See Figure 6-1 for typical quiescent current.
(3) Shaded cells indicate characteristic performance difference.
(4) The TMP300 is functional over this range and no indication of performance is implied.
