LM4041CIM3X-1.2/NOPB

Overview

The LM4041CIM3X-1.2/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring a fixed output of 1.225 V with an initial accuracy of ±0.5%. It operates within a temperature range of -40°C to +85°C and utilizes a SOT-23-3 surface-mount package. The device supports a wide operating current range from 45 µA to 12 mA and exhibits a typical output noise of 20 µVRMS. Designed for stability without external capacitors, it offers low dynamic impedance and a temperature coefficient of 150 ppm/°C.

Feature Summary

Eliminates the need for external stabilizing capacitors while ensuring stability with any capacitive load
Provides stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents through bandgap curvature correction
Utilizes fuse and Zener-zap reverse breakdown trim during wafer sort to ensure precise initial accuracy

Applications

Data acquisition systems
Power supply monitoring circuits
Instrumentation and test equipment

Procurement Notes

Verify the specific suffix 'CIM3X' corresponds to the C-grade (±0.5%) accuracy and industrial temperature range (-40°C to +85°C). Confirm the 'NOPB' designation indicates lead-free and RoHS compliance. Ensure the ordering code matches the required SOT-23-3 packaging format for your PCB layout constraints.

Selection Notes

Select this component when space-constrained designs require a sub-miniature SOT-23-3 package. Choose this model for applications needing a fixed 1.225 V reference with moderate precision (±0.5%). It is suitable for portable devices due to its micropower consumption and ability to operate without external compensation components.

Part Context

This part belongs to the LM4041-N family of precision micropower shunt voltage references. The series includes adjustable versions and various accuracy grades (A, B, C, D) packaged in SC-70, SOT-23, and TO-92 formats. The LM4041-N series is designed for battery-powered and space-critical applications requiring high stability and low power consumption.
