7 / 21 page TL431, TL432 Electrical characteristics Doc ID 4467 Rev 11 7/21 3.1 Reference input voltage deviation over temperature range ΔVref is defined as the difference between the maximum and minimum values obtained over the full temperature range. ΔVref = Vref max - Vref min Figure 6. Reference input voltage deviation over temperature range Table 5. TL431IY (Tamb = 25°C unless otherwise specified) Symbol Parameter TL431IY TL431AIY Unit Min.
