ATL43xLIxQ devices 10 27 mV
ΔVref / ΔVKA Ratio of change in reference voltage to the change in cathode voltage See Figure 18 IKA = 1 mA ΔVKA = 10 V - Vref –1.4 –2.7 mV/V
ΔVKA = 36 V - 10 V –1 –2 mV/V
Iref Reference Input Current See Figure 18 IKA = 1 mA, R1 = 10kΩ, R2 = ∞ 0.2 0.4 µA
II(dev) Deviation of reference input current over full temperature range (1) See Figure 18 IKA = 1 mA, R1 = 10kΩ, R2 = ∞ 0.1 0.3 µA
Imin Minimum cathode current for regulation See Figure 17 VKA = Vref 65 80 uA
Ioff Off-state cathode current See Figure 19 VKA = 36 V, Vref = 0 0.1 1 µA
|ZKA| Dynamic Impedance (2) See Figure 17 VKA = Vref, IKA = 1 mA to 15 mA 0.3 0.65 Ω
(1) The deviation parameters VI(dev) and II(dev) are defined as the differences between the maximum and minimum values obtained over the
rated temperature range. For more details on VI(dev) and how it relates to the average temperature coefficient, see Parameter Measurement Information.
(2) The dynamic impedance is defined by |ZKA| = ΔVKA/ΔIKA.  For more details on |ZKA| and how it relates to VKA, see Parameter Measurement Information.
