LM4041EEM3X-1.2/NOPB

Voltage Reference Overview

The LM4041EEM3X-1.2/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring a fixed output of 1.225 V. It utilizes an advanced design that ensures stability with any capacitive load without requiring an external stabilizing capacitor. The device operates within a temperature range of -40°C to +125°C and is housed in a sub-miniature SOT-23 surface-mount package.

Voltage Reference Feature Summary

• Eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load
• Provides high accuracy through fuse and Zener-zap reverse breakdown voltage trim during wafer sort
• Features bandgap reference temperature drift curvature correction for stable performance across wide operating temperatures

Voltage Reference Applications

• Space-critical applications requiring compact surface-mount solutions
• Portable equipment designs prioritizing low power consumption
• Precision measurement systems utilizing shunt regulation

Voltage Reference Procurement Notes

Verify the specific grade suffix (e.g., E) against official datasheets to confirm initial accuracy and temperature coefficient specifications. Ensure the ordering part number matches the required tolerance and thermal range. Confirm RoHS compliance status and packaging options such as tape and reel or cut tape availability directly with authorized distributors.

Voltage Reference Selection Notes

Select this component when a fixed 1.225 V reference is required in a small SOT-23 package. It is suitable for designs needing stability with capacitive loads without external compensation. Consider the operating current range and temperature coefficient requirements relative to the specific grade available for the application.

Voltage Reference Part Context

This device belongs to the LM4041-N family of precision voltage references from Texas Instruments. The family offers both fixed and adjustable versions in space-saving packages like SC-70 and SOT-23. These references are designed for portable applications and feature low dynamic impedance and low noise characteristics for stable operation over wide current and temperature ranges.

Voltage Reference Replacement Considerations

Compatible substitutes include other LM4041 variants with matching output voltages and package types, such as LM4041DEM3X-1.2/NOPB or LM4041CIM3X-1.2/NOPB, provided their accuracy grades and temperature ranges meet the design requirements.
