      Full temperature ranges are –40°C to 125°C for TLVH431Q, –40°C to 85°C for TLVH431I, and 0°C to 70°C for TLVH431C.
      (2)
      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,
      αVREF, is defined as:
      where
      ΔTA is the rated operating free-air temperature range of the device.
      αVREF can be positive or negative, depending on whether minimum VREF or maximum VREF, respectively, occurs at the lower
      temperature.
      (3)
      The dynamic impedance is defined as:
      When the device is operating with two external resistors (see Figure 2 ), the total dynamic impedance of the circuit is defined as:
