LM4050QAIM3-2.0/NOPB

Voltage Reference Overview

The LM4050QAIM3-2.0/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, designed for high precision applications. It provides a fixed output voltage of 2.048 V with an initial accuracy of 0.1%. The device features a temperature coefficient of 50 ppm/°C and operates within a junction temperature range of -40°C to +125°C. It supports a maximum cathode current of 15 mA and consumes a typical quiescent current of 65 µA. 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 the AEC-Q100 standard for robust performance in demanding environments.
• High precision voltage regulation achieved through tight initial accuracy tolerances and stable temperature coefficients.
• Ultra-low power consumption design enables extended battery life in portable and energy-efficient systems.

Voltage Reference Applications

• Portable instrumentation requiring precise analog-to-digital conversion references
• Battery-powered measurement devices needing low standby current
• Automotive electronic control units requiring qualified voltage references

Voltage Reference Procurement Notes

Verify the specific suffix codes against official Texas Instruments documentation to confirm exact electrical parameters and packaging options. Ensure compatibility with AEC-Q100 requirements if used in automotive contexts. Cross-reference datasheet revisions to validate updated specifications before finalizing procurement decisions.

Voltage Reference Selection Notes

Select this component when a 2.048 V reference with 0.1% accuracy is required in an SOT-23-3 package. Consider the 65 µA operating current for power-sensitive designs. Verify that the 50 ppm/°C temperature drift meets system thermal stability requirements across the specified industrial temperature range.

Voltage Reference Part Context

This part belongs to the LM4050-N series of micropower shunt voltage references from Texas Instruments. The 'Q' designation indicates automotive qualification, while 'AI' specifies the 2.048 V output voltage and 0.1% accuracy grade. The '/NOPB' suffix denotes lead-free and RoHS compliance.

Voltage Reference Replacement Considerations

LM4050QAIM3-2.5/NOPB offers identical form factor and accuracy but provides a 2.5 V output instead of 2.048 V. LM4050QCEM3-2.0/NOPB provides the same voltage but with lower 0.5% initial accuracy. Verify pinout compatibility and thermal characteristics when substituting.
