LM4050QBIM3X2.5/NOPB

Voltage Reference Overview

The LM4050QBIM3X2.5/NOPB is a micropower shunt voltage reference with a fixed output of 2.5V and an initial accuracy of ±0.5%. It operates within a temperature range of -40°C to +125°C and features a temperature coefficient of 50ppm/°C. The device supports a maximum cathode current of 15mA and draws only 80µA in quiescent operation. Packaged in a compact SOT-23-3 surface-mount case, it meets AEC-Q100 automotive qualification standards.

Voltage Reference Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards for robust performance in demanding environments
• Micropower architecture ensures minimal current consumption while maintaining precision voltage regulation
• Compact SOT-23-3 surface-mount package facilitates efficient PCB layout and space-constrained designs

Voltage Reference Applications

• Automotive electronic systems requiring stable reference voltages
• Portable battery-powered devices prioritizing low power consumption
• Precision measurement instruments needing accurate voltage references

Voltage Reference Procurement Notes

Verify the specific suffix 'Q' confirms automotive grade qualification and 'I' indicates industrial temperature range extension. Confirm the 'X' suffix matches the required tape-and-reel packaging format for automated assembly processes. Ensure compatibility with existing board footprints for SOT-23-3 packages during component sourcing.

Voltage Reference Selection Notes

Select this component when automotive certification is mandatory alongside tight tolerance requirements. The 50ppm/°C temperature coefficient suits applications experiencing moderate thermal variations. Consider the 15mA maximum current limit when designing biasing circuits to ensure stable operation without exceeding device specifications.

Voltage Reference Part Context

This part belongs to the LM4050-N series of micropower shunt voltage references from Texas Instruments. It shares the core architectural design with other variants in the family but is distinguished by its specific 2.5V output voltage and automotive-grade qualification. The series offers multiple voltage options and accuracy grades to suit diverse precision reference needs.

Voltage Reference Replacement Considerations

LM4050QBEM3X2.5/NOPB provides higher accuracy at ±0.2% tolerance with identical pinout and automotive qualification.
