LM4040D25QDBZR

Overview

The LM4040D25QDBZR is a precision micropower shunt voltage reference from Texas Instruments, featuring a fixed output of 2.5 V with an initial accuracy of ±1%. Packaged in a surface-mount SOT-23-3 case, it operates within a temperature range of -40°C to +125°C and supports a maximum shunt current of 15 mA. The device exhibits a temperature coefficient of 150 ppm/°C and meets AEC-Q100 automotive qualification standards for Grade 1.

Feature Summary

Automotive-grade reliability compliant with AEC-Q100 standards
Wide operating temperature range suitable for harsh environments
Micropower consumption with low minimum cathode current
Compact surface-mount packaging for space-constrained designs

Applications

Automotive sensor signal conditioning circuits
Portable battery-powered instrumentation
Data acquisition systems requiring stable reference voltages
Microcontroller analog-to-digital converter references

Procurement Notes

Verify the specific suffix 'Q' confirms AEC-Q100 automotive qualification status against the official datasheet. Confirm the package marking and pinout match the SOT-23-3 specification. Ensure the supply chain source provides valid traceability documentation required for automotive assembly processes.

Selection Notes

Select this component when automotive certification is mandatory alongside precise 2.5 V referencing. Compare the 150 ppm/°C temperature drift against tighter stability requirements. Evaluate the SOT-23-3 footprint constraints against available PCB real estate. Consider the 15 mA maximum current limit for load regulation needs.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references. It shares architectural similarities with other LM4040 variants but is distinguished by its automotive qualification and specific 2.5 V output tolerance. The family offers various voltage options and accuracy grades for diverse industrial applications.
