UNIT Minimum Cathode current for Regulation VZ=VREF (Fig. 1) IZ(MIN) 0.25 0.5 mA Off-State Current VZ=20V, VREF =0V (Fig. 3) IZ(OFF) 0.1 1.0 µA Dynamic Output Impedance (Note 4) VZ=VREF Frequency= 0Hz (Fig. 1) RZ 0.08 0.3 Ω T2 T1 VMAX VDEV = VMAX-VMIN VMIN TEMPERATURE Note 3. Deviation of reference input voltage, V DEV, is de- fined as the maximum variation of the reference input voltage over the full temperature range. The average temperature coefficient of the reference in- put voltage, αV REF is d efined as: T1 T2 10 C) 25 (at V V T1 T2 6 10 C) 25 (at V V - V C ppm V 6 REF DEV REF MIN MAX REF − ° ± = − ° ± = ° ∆ Where: T2−T1=full temperature change. αV REF can be positive or negative depending on whether the slope is positive or negative. Example: VDEV= 9.0mV, VREF= 2495mV, T2−T1= 70°C, slope is negative. C 50ppm/ V C 70 6 10 2495mV 9.0mV REF ° − = = ° α Note 4. The dynamic output impedance, Rz, is de- fined as: RZ = Z Z V I ∆ ∆ When the device is programmed with two external re- sistors, R1 and R2, (see Fig. 2), the dynamic output impedance of the overall circuit, is defined as: [ ] R2 R1 1 Rz Iz Vz z r + ≅ ∆ ∆ = n TYPICAL PERFORMANCE CHARACTERISTICS -1.0 -0.5 0.0 0.5 1.0 1.5 2.0 2.5 3.0 -600 -400 -200 0 200 400 600 800 1000 IZ(MIN) VZ =VREF TA =25°C Cathode Current vs Cathode Voltage Cathode Voltage (V) -40 -20 0 20 40 60 80 100 120 2.40 2.42 2.44 2.46 2.48 2.50 2.52 2.54 2.56 2.58 Reference Voltage vs Temperature VZ =VREF IZ =10mA Temperature (°C) VREF=2.535V VREF=2.495V VREF=2.455V |
