LM4041DIM3X-1.2/E7002631

Voltage Reference Overview

The LM4041DIM3X-1.2 is a precision micropower shunt voltage reference manufactured by Texas Instruments, housed in an SOT-23 surface-mount package. It provides a fixed output voltage of 1.225 V with an initial accuracy of ±0.1% at 25°C and a maximum temperature coefficient of 100 ppm/°C. The device operates within a wide current range from a minimum of 60 µA to a maximum of 12 mA. It functions reliably across an extended industrial temperature range of -40°C to +125°C without requiring external stabilizing capacitors.

Voltage Reference Feature Summary

• Eliminates the need for external stabilizing capacitors while ensuring stability with any capacitive load
• Utilizes fuse and Zener-zap reverse breakdown trim during wafer sort to ensure high accuracy
• Features bandgap reference temperature drift curvature correction for stable performance over wide operating temperatures

Voltage Reference Applications

• Space-critical applications utilizing sub-miniature packages
• Portable devices requiring low power consumption
• Precision measurement systems demanding stable reference voltages

Voltage Reference Procurement Notes

Verify the specific suffix E7002631 against official Texas Instruments documentation to confirm it denotes a standard commercial variant or a specific customer-specific marking. Ensure the ordering part number matches the exact electrical grade and package type required for your design. Cross-reference the datasheet revision history to confirm component availability and manufacturing status before finalizing procurement plans.

Voltage Reference Selection Notes

Select this component when space constraints necessitate the use of an SOT-23 package alongside the requirement for high precision. The fixed 1.225 V output is suitable for low-voltage reference applications. Consider the 60 µA minimum operating current for battery-powered designs where quiescent current must be minimized. Verify that the 12 mA maximum cathode current aligns with the power dissipation capabilities of the target PCB layout.

Voltage Reference Part Context

This device belongs to the LM4041-N family of precision voltage references, which are designed for applications requiring small form factors. The family includes both fixed and adjustable versions available in SC-70 and SOT-23 packages. These references are characterized by their ability to operate stably without external capacitors, simplifying circuit design for portable and space-constrained electronic equipment.
