LM4050QBIM3-5.0/NOPB

Voltage Reference Overview

The LM4050QBIM3-5.0/NOPB is a micropower shunt voltage reference from Texas Instruments, part of the LM4040/LM4050 family. It provides a fixed 5V output with an initial accuracy of ±0.2%. The device operates within a temperature range of -40°C to +125°C and features a temperature coefficient of 40 ppm/°C. It utilizes a SOT-23 surface-mount package with three pins. The maximum cathode current is 15 mA, and it meets AEC-Q100 automotive qualification standards.

Voltage Reference Feature Summary

Provides stable fixed voltage reference for precision applications
Automotive qualified under AEC-Q100 standards
Micropower operation suitable for battery-powered systems
Compact SOT-23 surface-mount packaging

Voltage Reference Applications

Portable instrumentation requiring high stability
Battery-powered measurement devices
Precision data acquisition systems
Reference sources for analog-to-digital converters

Voltage Reference Procurement Notes

Verify the specific suffix 'Q' indicates automotive grade qualification and 'B' denotes the ±0.2% accuracy tier. Confirm the 'NOPB' suffix ensures lead-free and RoHS compliance. Ensure the ordering code matches the required 5.0V output and SOT-23-3 package type. Cross-reference the full part number against official Texas Instruments documentation to confirm current production status and availability.

Voltage Reference Selection Notes

Select this component when automotive reliability and tight initial accuracy are required in a compact form factor. The low temperature coefficient of 40 ppm/°C makes it suitable for environments with significant thermal variation. Compare against standard industrial grades if automotive certification is not mandatory. Consider the 15 mA maximum current limit when designing the biasing circuit for the intended load.

Voltage Reference Part Context

This device belongs to the LM4040/LM4050 series of micropower shunt voltage references. The LM4050 variant typically offers improved performance characteristics compared to the LM4040. The 'Q' prefix signifies automotive-grade manufacturing, while the 'B' suffix specifies the tighter tolerance band. This family is designed to replace larger, less efficient reference solutions in space-constrained designs.
