LM4050QBIM3-2.0/NOPB

Voltage Reference Overview

The LM4050QBIM3-2.0/NOPB is a micropower shunt voltage reference from Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It provides a fixed output voltage of 2.048 V with an initial accuracy of 0.5% and a temperature coefficient of 50 ppm/°C. The device operates within a junction temperature range of -40°C to +125°C and features a maximum shunt current of 15 mA. Packaged in a compact SOT-23-3 surface-mount case, it supports reel and cut tape formats.

Voltage Reference Feature Summary

• Automotive-grade reliability certified under the AEC-Q100 standard for robust performance in vehicle environments.
• Micropower architecture enables low cathode current consumption, optimizing efficiency in battery-powered systems.
• Precision shunt regulation maintains stable reference voltage across wide industrial and automotive temperature extremes.

Voltage Reference Applications

• Automotive electronic control units requiring precise voltage references
• Data acquisition systems needing stable analog-to-digital converter references
• Portable instrumentation benefiting from low-power precision regulation

Voltage Reference Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeits. Confirm AEC-Q100 compliance and specific suffix variations match design requirements. Check datasheet revisions for any parameter updates. Ensure storage conditions adhere to moisture sensitivity level specifications before assembly.

Voltage Reference Selection Notes

Select this part when automotive qualification and high precision are required in a small footprint. Compare against LM4050QA series for tighter tolerance needs or LM4050QCEM3 variants for different voltage outputs. Verify input voltage exceeds the reference output by sufficient headroom for proper shunt operation.

Voltage Reference Part Context

This component belongs to the LM4050-N/Q1 family of micropower shunt voltage references. It shares architectural similarities with other members like the LM4050QBEM3-2.5/NOPB but offers a specific 2.048 V output option tailored for digital logic interfacing and ADC reference applications in automotive contexts.

Voltage Reference Replacement Considerations

LM4050QBIM3-2.0/NOPB is functionally equivalent to LM4050QBIM3-2.0 without the NOPB suffix if lead-free status is not critical. Direct pin-compatible alternatives within the same family include LM4050QAEM3-2.0/NOPB for higher accuracy or LM4050QCEM3-2.0/NOPB for commercial grade.
