6.6 Electrical Characteristics: TL43xA-Q1

over recommended operating conditions, TA = 25°C (unless otherwise noted)
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
VREF Reference voltage VKA = VREF, IKA = 10 mA, see Figure 20 2470 2495 2520 mV
VI(DEV) Deviation of reference voltage over full temperature(1) VKA = VREF, IKA = 10 mA, TA = –40°C to 125°C,
see Figure 20 		14 34 mV
ΔVREF/ΔVKA Ratio of change in reference voltage to the change in cathode voltage IKA = 10 mA,
see Figure 21 		ΔVKA = 10 V – VREF –1.4 –2.7 mV/V
ΔVKA = 36 V – 10 V –1 –2
IREF Reference current IKA = 10 mA, R1 = 10 kΩ, R2 = ∞, see Figure 21 2 4 µA
II(DEV) Deviation of reference current over full temperature(1) IKA = 10 mA, R1 = 10 kΩ, R2 = ∞,
TA = –40°C to 125°C, see Figure 21 		0.8 2.5 µA
IMIN Minimum cathode current for regulation VKA = VREF, see Figure 20 0.4 0.7 mA
IOFF OFF-state cathode current VKA = 36 V, VREF = 0, see Figure 22 0.1 0.5 µA
|ZKA| Dynamic impedance(1) IKA = 1 mA to 100 mA, VKA = VREF, f ≤ 1 kHz,
see Figure 20 		0.2 0.5 Ω
(1) The deviation parameters (VI(DEV) and II(DEV)) are defined as the differences between the maximum and minimum values obtained over the recommended temperature range.
