LM4041DIM7X-ADJ

Voltage Reference Overview

The LM4041DIM7X-ADJ is a precision micropower shunt voltage reference manufactured by Texas Instruments, formerly National Semiconductor. It provides an adjustable reverse breakdown voltage and operates within a current range of 60 µA to 12 mA. The device utilizes SC-70 (SOT-353) surface-mount packaging for space-constrained designs. It features bandgap temperature drift curvature correction and low dynamic impedance to ensure stable accuracy across wide operating temperatures and currents.

Voltage Reference Feature Summary

• Eliminates the need for external stabilizing capacitors while ensuring stability with any capacitive load
• Offers fixed and adjustable reverse breakdown voltage options for design flexibility
• Uses fuse and Zener-zap reverse breakdown or reference voltage trim during wafer sort to ensure high accuracy

Voltage Reference Applications

• Space-critical applications requiring sub-miniature packages
• Battery-powered systems utilizing micropower operation
• Precision measurement circuits requiring stable voltage references

Voltage Reference Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the package type is SC-70 (SOT-353) and the suffix indicates the adjustable variant. Ensure the NOPB suffix is present if lead-free compliance is required. Cross-reference the specific ordering code against official TI documentation to confirm availability and exact electrical tolerances.

Voltage Reference Selection Notes

Select this component when a small footprint is critical and an adjustable reference voltage is needed. It serves as a pin-for-pin compatible alternative to standard LM4041 variants in SOT-23 and SC-70 packages. Consider the minimum operating current of 60 µA for low-power budgeting. Verify that the required accuracy grade matches the available A or D grades specified in the datasheet.
