Load regulation is how the analog output voltage of the ISOTMP35 changes as the output load current changes, and is measured across temperature. Load regulation is important because when implementing the ISOTMP35 with an ADC, the user can use an RC filter on the analog output. Knowing how the output voltage changes based on the current pulled with different resistive and capacitive loads help the user make accurate temperature measurements with the ISOTMP35. See Figure 5-5 for more details on Load Regulation and Section 7.1.6 for more details on how to use the ISOTMP35 with an ADC.
