3 / 20 page LM4030 www.ti.com SNVS552B – MARCH 2008 – REVISED APRIL 2013 Electrical Characteristics LM4030-2.5 (VOUT = 2.5V) Limits in standard type are for TJ = 25°C only, and limits in boldface type apply over the junction temperature (TJ) range of - 40°C to +125°C. Minimum and Maximum limits are ensured through test, design, or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only. Symbol Parameter Conditions Min (1) Typ (2) Max (1) Unit VREF Reverse Breakdown Voltage ISHUNT = 120µA 2.5 V Reverse Breakdown Voltage Tolerance (ISHUNT = 120µA) LM4030A-2.5 (A Grade - 0.05%) -0.05 0.05 % LM4030B-2.5 (B Grade - 0.10%) -0.10 0.10 % LM4030C-2.5 (C Grade - 0.15%) -0.15 0.15 % IRMIN Minimum Operating Current 120 µA TC Temperature Coefficient (3) LM4030A-2.5 0°C ≤ TJ ≤ + 85°C 10 ppm / °C -40°C ≤ TJ ≤ +125°C 20 ppm / °C LM4030B-2.5 -40°C ≤ TJ ≤ +125°C 20 ppm / °C LM4030C-2.5 -40°C ≤ TJ ≤ +125°C 30 ppm / °C ΔVREF/ΔISHUNT Reverse Breakdown Voltage Change 160µA ≤ ISHUNT ≤ 30mA 25 110 ppm / mA with Current ΔVREF Long Term Stability (4) 1000 Hrs, TA = 30°C 40 ppm VHYST Thermal Hysteresis (5) -40°C ≤ TJ ≤ +125°C 75 ppm VN Output Noise Voltage (6) 0.1 Hz to 10 Hz 105 µVPP (1) Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation using Statistical Quality Control. (2) Typical numbers are at 25°C and represent the most likely parametric norm. (3) Temperature coefficient is measured by the "Box" method; i.e., the maximum ΔVREF is divided by the maximum ΔT. (4) Long term stability is VREF @25°C measured during 1000 hrs. This measurement is taken for IR = 500 µA. (5) Thermal hysteresis is defined as the change in +25°C output voltage before and after cycling the device from (-40°C to 125°C) eight times. (6) Low frequency peak-to-peak noise measured using first-order 0.1 Hz HPF and second-order 10 Hz LPF. Electrical Characteristics LM4030-4.096 (VOUT = 4.096V) Limits in standard type are for TJ = 25°C only, and limits in boldface type apply over the junction temperature (TJ) range of - 40°C to +125°C. Minimum and Maximum limits are ensured through test, design, or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only.
