Limits are specified to TI's AOQL (Average Outgoing Quality Level).
(2)
Accuracy is defined as the error between the measured and reference output voltages, tabulated in the TMP235 Transfer Table and
TMP236 Transfer Table at the specified conditions of supply voltage and temperature (expressed in °C). Accuracy limits include line
regulation within the specified conditions. Accuracy limits do not include load regulation; they assume no DC load.
6.5 Electrical Characteristics
TMP235: VDD = 2.3 V to 5.5 V, GND = Ground, TA = –40°C to +125°C and no load (unless otherwise noted)
TMP236: VDD = 3.1 V to 5.5 V, GND = Ground, TA = –10°C to +125°C and no load (unless otherwise noted)
