The LM4040QEEM3-3.0/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 3.0 V with an initial accuracy of ±1%. Packaged in a compact SOT-23-3 surface-mount format, it operates within a temperature range of -40°C to +85°C. The device features a maximum cathode current of 15 mA and a minimum operating current of 70 µA. It exhibits a temperature coefficient of 150 ppm/°C and meets AEC-Q100 automotive qualification standards for reliability.
Verify the specific suffix 'QEE' against official Texas Instruments documentation to confirm automotive grade classification and exact tolerance specifications. Ensure the ordering part number matches the required package variant and temperature rating. Cross-reference the datasheet revision date to validate current manufacturing status and compliance with RoHS directives before finalizing procurement.
Select this component when automotive qualification is mandatory alongside precise 3.0 V referencing. Compare the 150 ppm/°C temperature coefficient against stricter requirements; if higher precision is needed, consider the LM4040B or LM4040E series variants. Evaluate the 70 µA minimum current constraint against circuit load conditions to ensure stable regulation without excessive power dissipation during standby modes.
This part belongs to the LM4040-N family of micropower shunt voltage references. It shares architectural similarities with other LM4040 variants but distinguishes itself through automotive qualification (AEC-Q100) and specific output voltage options. The family offers various accuracy grades and voltage outputs to suit diverse industrial and consumer applications.
LM4040DIM3-3.0/NOPB provides equivalent electrical performance in the same package but lacks automotive qualification. LM4040BIM3-3.0/NOPB offers superior accuracy at ±0.2% but may not meet automotive reliability standards. Verify pinout compatibility and thermal characteristics when substituting.
