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. NOTES: 1. All voltage values are with respect to the anode terminal. 2. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) − TA)/θJA. Operating at the absolute maximum TJ of 150°C can impact reliability. 3. The package thermal impedance is calculated in accordance with JESD 51-7. recommended operating conditions VZ IZ Regulator voltage TA Operating free-air temperature range Regulator current TL430C MIN MAX Vref 2 30 UNIT V 100 mA 0 70 °C electrical characteristics over recommended operating conditions, TA = 25°C (unless otherwise noted) TEST FIGURE PARAMETER TEST CONDITIONS VI(ref) Reference input voltage 1 VZ = VI(ref), VZ = VI(ref), TA = 0°C to 70°C IZ = 10 mA IZ = 10 mA, αVI(ref) Temperature coefficient of reference input voltage 1 II(ref) Reference input current 2 IZ = 10 mA, R2 = ∞ R1 = 10 kΩ, IZK Regulator current near lower knee of regulation range 1 VZ = VI(ref) IZK Regulator current at maximum limit of regulation range 1 VZ = VI(ref) VZ = 5 V to 30 V, rz Differential regulator resistance (see Note 5) 1 VZ = VI(ref), ∆IZ = (52 − 2) mA Vn Noise voltage 2 f = 0.1 Hz to 10 Hz 2 TL430C MIN TYP MAX 2.5 2.75 3 120 UNIT V ppm/°C 3 10 µA 0.5 2 mA 50 See Note 4 mA 100 1.5 VZ = 3 V VZ = 12 V 3 Ω 50 200 µV VZ = 30 V 650 NOTES: 4.
