LM4041DIM7-ADJ/NOPB

Voltage Reference Overview

The LM4041DIM7-ADJ/NOPB is a precision micropower shunt voltage reference by Texas Instruments, housed in an SC-70-5 surface-mount package. It features adjustable output voltage with an initial accuracy of 1% and a temperature coefficient of 150 ppm/°C. The device operates within a current range of 4.5 µA to 12 mA and functions across a temperature range of -40°C to +125°C.

Voltage Reference Feature Summary

• Eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load
• Utilizes fuse and Zener-zap reverse breakdown or reference voltage trim during wafer sort for high accuracy
• Bandgap reference temperature drift curvature correction ensures stable performance over wide operating ranges

Voltage Reference Applications

• Space-critical applications requiring sub-miniature packaging
• Battery-powered systems due to low quiescent current
• Precision measurement circuits requiring stable reference voltages

Voltage Reference Procurement Notes

Verify the specific suffix ADJ indicates the adjustable version when ordering. Confirm the NOPB designation ensures compliance with RoHS standards and absence of lead-based materials. Check the SC-70-5 package outline against PCB footprint requirements to ensure mechanical compatibility before finalizing procurement specifications.

Voltage Reference Selection Notes

Select this component when space constraints necessitate an SC-70-5 package over larger alternatives like SOT-23. Choose the adjustable variant when a specific non-standard reference voltage is required rather than fixed options. Ensure the application current remains within the 4.5 µA to 12 mA operational window to maintain specified accuracy and stability levels.

Voltage Reference Part Context

This part belongs to the LM4041-N series of precision voltage references designed for micropower applications. The series includes both fixed and adjustable versions available in SC-70 and SOT-23 packages. The LM4041-N family is engineered to provide high stability without external compensation components, making it suitable for compact electronic designs.
