LM4040EIM3X-2.5/NOPB

Overview

The LM4040EIM3X-2.5/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, housed in a 3-pin SOT-23 package. It provides a fixed output voltage of 2.5 V with an initial accuracy of 1%. The device features a temperature coefficient of 150 ppm/°C and operates within a junction temperature range of -40°C to +85°C. It supports a maximum cathode current of 15 mA and requires a minimum operating current of 60 µA.

Feature Summary

• Provides stable reference voltage via shunt regulation architecture
• Designed for low power consumption applications
• Suitable for surface-mount assembly processes

Applications

• Portable battery-powered instrumentation
• Data acquisition systems
• Handheld meters

Procurement Notes

Verify the specific suffix 'E' indicates the 1% accuracy grade and 'X' denotes tape-and-reel packaging. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering part number matches the required temperature range and package type for your design specifications.

Selection Notes

Select this component when a 2.5 V reference with 1% initial accuracy is required. It is appropriate for designs prioritizing low quiescent current over high precision. Consider higher accuracy grades if tighter tolerance is needed.

Part Context

This part belongs to the LM4040-N family of micropower shunt voltage references. It serves as a compact alternative to larger packages while maintaining similar electrical characteristics. The series is widely used in general-purpose analog circuits requiring a stable voltage baseline.

Replacement Considerations
