LM4040CEM3-2.5/NOPB

Overview

The LM4040CEM3-2.5/NOPB is a micropower shunt voltage reference with a nominal output of 2.5 V and an initial accuracy of ±1%. It operates within a temperature range of -40°C to +85°C, featuring a maximum temperature coefficient of 100 ppm/°C. The device supports a maximum cathode current of 15 mA and draws a minimum operating current of 65 µA. Packaged in a surface-mount SOT-23-3 format, it provides stable reference performance for precision applications.

Feature Summary

Micropower operation with low minimum operating current
Shunt topology for precise voltage regulation
Temperature-stable reference output

Applications

Portable instrumentation circuits
Battery-powered measurement systems
Data acquisition signal conditioning

Procurement Notes

Verify the specific suffix 'CEM3' against official Texas Instruments documentation to confirm package type and temperature grade. Ensure the part number matches the exact datasheet revision required for your design. Cross-reference the manufacturer's latest ordering information to validate availability and compliance status before finalizing procurement plans.

Selection Notes

Select this component when a compact surface-mount voltage reference is required for low-power designs. The SOT-23-3 package suits space-constrained PCB layouts. Verify that the 15 mA maximum current capability meets the load requirements of the target circuit application.

Part Context

This part belongs to the LM4040-N series of micropower shunt voltage references from Texas Instruments. The series offers various fixed voltage options and accuracy grades. The LM4040CEM3 variant specifically utilizes the SOT-23-3 package for surface-mount integration.

Replacement Considerations

Check for LM4040CIM3-2.5/NOPB or LM4040AIM3-2.5/NOPB as potential alternatives within the same family. Confirm pinout compatibility and electrical parameter alignment with the original design specifications.
