LM4041BIM3-1.2/NOPB

Overview

The LM4041BIM3-1.2/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed 1.225 V output. It features an initial accuracy of ±0.2% at 25°C and a maximum temperature coefficient of 100 ppm/°C. The device operates within a supply current range of 45 µA to 12 mA and functions across an extended temperature range of -40°C to +125°C. Packaged in a surface-mount SOT-23-3 format, it eliminates the need for external stabilizing capacitors while maintaining stability with any capacitive load.

Feature Summary

Fixed 1.225 V precision output with high initial accuracy
Stable operation with any capacitive load without external components
Ultra-low operating current suitable for power-constrained designs

Applications

Portable battery-powered equipment
Handheld instruments
Microprocessor supervisory circuits
Data acquisition systems

Procurement Notes

Verify that the ordering suffix matches the required grade and package configuration. Confirm the specific temperature range designation aligns with application requirements. Ensure the NOPB suffix indicates lead-free and RoHS compliance status as specified by the manufacturer. Cross-reference the part number against official distributor catalogs to confirm availability and authenticity before procurement.

Selection Notes

Select this component when space-saving surface-mount packaging is required alongside high precision. Choose the B-grade variant for applications demanding tighter initial accuracy tolerances compared to standard C or D grades. Consider the low minimum operating current for efficiency in battery-operated devices where quiescent power consumption is critical.

Part Context

This part belongs to the LM4041-N family of micropower shunt references. It shares core architectural features with other variants in the series, differing primarily in accuracy grade, temperature range, and package type. The BIM3 designation specifically denotes the B-grade accuracy level housed in the SOT-23-3 surface-mount package.
