NOTES:
4. Full range is –40
°C to 85°C for the TLV431I, and 0°C to 70°C for the TLV431C.
5. The deviation parameters Vref(dev) and Iref(dev) are defined as the differences between the maximum and minimum values obtained
over the rated temperature range. The average full-range temperature coefficient of the reference input voltage,
a
