LM4040CEM3X-2.5

Overview

The LM4040CEM3X-2.5 is a micropower shunt voltage reference from the LM4040-N series by Texas Instruments, housed in a SOT-23 package. It provides a fixed output of 2.5 V with an initial accuracy of ±1%. The device operates over a temperature range of -40°C to +85°C and features a maximum shunt current of 15 mA.

Feature Summary

Micropower operation for energy efficiency
Precision voltage regulation
Compact surface-mount packaging

Applications

Portable instrumentation
Battery-powered systems
Data acquisition circuits

Procurement Notes

Verify the specific suffix 'EM3X' against official TI documentation to confirm tape-and-reel packaging and exact grade specifications. Ensure compatibility with existing PCB footprints and thermal management requirements during integration.

Selection Notes

Select this component when a stable 2.5 V reference is required in space-constrained designs. Consider the ±1% tolerance and 150 ppm/°C temperature coefficient for circuit stability. Verify that the 15 mA maximum current meets load requirements.

Part Context

Part of the LM4040-N family of precision shunt references. Designed as a drop-in replacement for older discrete zener diodes, offering superior stability and lower noise in compact SOT-23 form factors for modern electronics.
