LM4040QEEM3-2.5/NOPB

Overview

The LM4040QEEM3-2.5/NOPB is a precision micropower shunt voltage reference from Texas Instruments, providing a fixed output of 2.5 V. It features an initial accuracy of 1% and a temperature coefficient of 150 ppm/°C. The device operates within a junction temperature range of -40°C to +125°C and supports a maximum shunt current of 15 mA. Packaged in a compact SOT-23-3 surface-mount format, it is qualified under the AEC-Q100 automotive standard for reliability in demanding environments.

Feature Summary

AEC-Q100 qualified for automotive applications
Micropower shunt regulation architecture
Extended industrial temperature range operation

Applications

Automotive electronic systems requiring stable voltage references
Portable battery-powered instrumentation
Data acquisition systems with high precision requirements

Procurement Notes

Verify the specific suffix 'Q' confirms AEC-Q100 automotive qualification status directly on the manufacturer datasheet. Ensure the package designation matches the required SOT-23 footprint for PCB layout compatibility. Confirm that the 1% initial accuracy meets the system tolerance specifications before finalizing procurement orders.

Selection Notes

Select this component when automotive reliability standards are mandatory alongside low power consumption. The 2.5 V output suits ADC/DAC reference needs where moderate accuracy is acceptable. Consider the SOT-23 size constraints against thermal dissipation requirements in enclosed automotive enclosures.

Part Context

This part belongs to the LM4040-N family of micropower shunt references. The 'Q' prefix denotes automotive grade qualification, distinguishing it from commercial variants like the LM4040EIM3. It shares functional similarities with the LM4041 series but offers different voltage options and package configurations tailored for space-constrained designs.
