LM4128AQ1MF2.5/NOPB

Voltage Reference Overview

The LM4128AQ1MF2.5/NOPB is a micropower series voltage reference manufactured by Texas Instruments, operating within an automotive temperature range of -40°C to +125°C. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.1% and a maximum shunt current of 20 mA. The device features a low supply current of 60 µA and operates from input voltages up to 6 V. Packaged in a compact SOT-23-5 surface-mount case, it meets AEC-Q100 qualification standards for automotive applications.

Voltage Reference Feature Summary

• Automotive-grade reliability certified under the AEC-Q100 standard
• Micropower operation with a typical supply current of 60 µA
• High precision performance with 0.1% initial accuracy tolerance

Voltage Reference Applications

• Automotive electronic systems requiring stable voltage references
• Precision analog-to-digital converter (ADC) reference inputs
• Data acquisition systems in harsh thermal environments

Voltage Reference Procurement Notes

Verify that the ordering suffix 'NOPB' confirms lead-free and RoHS compliance status as specified by the manufacturer. Confirm the package designation matches the required SOT-23-5 footprint for PCB layout compatibility. Ensure the component grade aligns with specific automotive quality requirements before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a fixed 2.5 V reference is required for automotive circuits demanding high initial accuracy. The SOT-23-5 package offers space efficiency for dense layouts. Consider the 60 µA quiescent current for battery-powered applications where power conservation is critical alongside precision stability.

Voltage Reference Part Context

This part belongs to the LM4128 family of micropower series voltage references. It shares functional similarities with other members like the LM4128BMF and LM4128AMFX but is distinguished by its automotive qualification and specific 0.1% accuracy class. The family utilizes a bandgap reference architecture optimized for low power consumption.

Voltage Reference Replacement Considerations

LM4128AQ1MFX2.5/NOPB serves as a reel-pack alternative to the cut-tape MF variant.
