These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2011, February, Rev. 02 TL432 Electrical Characteristics Ta= 25°C (unless otherwise noted) Symbol Parameter VRFF Reference voltage VDEV VREF Temp Deviation ∆VREF/∆VKA Ratio of Change in VREF to Change in Cathode Voltage IREF Reference Input Current IREF(DEV) IREF Temp Deviation Ik(off) Off-state cathode current Zka IK(MIN) Dynamic Output Impedance Minimum Operating Current Test Conditions VKA=VREF, lK=10mA (Fig. 1) TA =25°C TL432 (2%) TL432-A (1%) TL432-C (0.5%) TA=full range (see Note1) VKA=VREF, lK=10mA (Fig. 1) !K=10mA, VKA=15V to VREF (Fig. 2) IK=10mA, R1 =10kΩ R2=∞ (Fig.2) TK=full range (see Note 1), R1 =10kΩ, R2=∞, IK=10mA (Fig. 2) VREF=0 V,(Fig.3) Vk=15V Vka=Vref, Ik=1mA to 100mA F ≤1kHz (Fig. 1) VKA=VREF(Fig. 1) Min TL432 Typ Max 1.216 1.228 1.234 1.240 1.240 1.240 1.264 1.252 1.246 10 25 mV -1 -2.7 mV / V 0.5 1.0 µA 0.05 0.3 µA 0.04 0.5 µA 0.2 0.4 Ω 60 80 µA Unit V Notes: 1.
