LM4040QEIM3X2.5/NOPB

Overview

The LM4040QEIM3X2.5/NOPB is a micropower shunt voltage reference from Texas Instruments, designed for precision applications requiring stable DC voltages. It provides a fixed output of 2.5 V with an initial accuracy of 1%. The device operates within a temperature range of -40°C to +125°C and features a maximum shunt current of 15 mA. It is housed in a compact SOT-23-3 surface-mount package and meets AEC-Q100 automotive qualification standards.

Feature Summary

Automotive-grade reliability certified under AEC-Q100 standards
Micropower operation suitable for battery-powered systems
High-temperature stability across extended industrial ranges

Applications

Automotive electronic control units
Precision measurement instrumentation
Battery management systems

Procurement Notes

Verify the specific suffix 'Q' indicates AEC-Q100 automotive qualification and 'X' denotes tape-and-reel packaging configuration. Confirm that the 1% initial accuracy aligns with system tolerance requirements. Ensure the SOT-23-3 footprint matches the PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when automotive certification and high-temperature operation are mandatory. The 2.5 V output is optimal for interfacing with ADCs and DACs requiring mid-rail references. Consider the 15 mA current limit for load driving capabilities and ensure thermal dissipation fits within the SOT-23 package limitations.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. It serves as a stable reference element in power management circuits. The Q prefix signifies automotive grade compliance, while the EIM3 variant specifies the SOT-23 surface-mount package type used in modern compact electronics designs.
