(1) Accuracy is defined as the error between the measured and reference output voltages, tabulated in the TMP235 Transfer Tableand 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.
