LM4030 www.ti.com SNVS552B – MARCH 2008 – REVISED APRIL 2013 LM4030 SOT-23 Ultra-High Precision Shunt Voltage Reference Check for Samples: LM4030 FEATURES DESCRIPTION • • • • • • • • • The LM4030 is an ultra-high precision shunt voltage reference, having exceptionally high initial accuracy (0.05%) and temperature stability (10ppm/°C). The LM4030 is available with fixed voltage options of 2.5V and 4.096V. Despite the tiny SOT-23 package, the LM4030 exhibits excellent thermal hysteresis (75ppm) and long-term stability (40ppm) as well as immunity to board stress effects. 1 2 High Output Voltage Accuracy 0.05% Low Temperature Coefficient 10 ppm/°C Extended Temperature Operation -40-125°C Excellent Thermal Hysteresis, 75ppm Excellent Long-Term Stability, 40ppm High Immunity to Board Stress Effects Capable of Handling 50 mA Transients Voltage Options 2.5V, 4.096V SOT-23 Package The LM4030 is designed to operate without an external capacitor, but any capacitor up to 10µF may be used. The LM4030 can be powered off as little as 120µA (max) but is capable of shunting up to 30mA continuously. As with any shunt reference, the LM4030 can be powered off of virtually any supply and is a simple way to generate a highly accurate system reference. APPLICATIONS • • • • • • Data Acquisition/Signal path Test and Measurement Automotive & Industrial Communications Instrumentation Power Management The LM4030 is available in three grades (A, B, and C). The best grade devices (A) have an initial accuracy of 0.05% with ensured temperature coefficient of 10 ppm/°C or less, while the lowest grade parts (C) have an initial accuracy of 0.15% and a temperature coefficient of 30 ppm/°C.

Operating Ratings indicate conditions for which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications, see Electrical Characteristics. If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. Without PCB copper enhancements. The maximum power dissipation must be de-rated at elevated temperatures and is limited by TJMAX (maximum junction temperature), θJ-A (junction to ambient thermal resistance) and TA (ambient temperature). The maximum power dissipation at any temperature is: PDissMAX = (TJMAX - TA) /θJ-A up to the value listed in the Absolute Maximum Ratings. θJ-A for SOT-23 package is 220°C/W, TJMAX = 125°C. The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin. Operating Ratings Maximum Continuous Shunt Current 30mA Maximum Shunt Current (
