LM4040EEM3-2.5/NOPB

Overview

The LM4040EEM3-2.5/NOPB is a precision micropower shunt voltage reference from Texas Instruments, providing a nominal output of 2.5 V. It operates within an extended temperature range of -40 °C to +125 °C and features a maximum shunt current of 15 mA. The device utilizes a SOT-23 (TO-236AB) surface-mount package with three pins. Initial accuracy specifications indicate a maximum output variation between 2.412 V and 2.588 V around the nominal value.

Feature Summary

Extended high-temperature operation capability up to 125 °C
Micropower consumption suitable for battery-powered applications
Compact SOT-23 surface-mount packaging

Applications

Portable instrumentation requiring stable voltage references
Battery-operated measurement systems
Temperature-compensated circuits in harsh environments

Procurement Notes

Verify the specific suffix EEM3 corresponds to the SOT-23 thin-profile shrink pitch package when sourcing. Confirm that the NOPB designation ensures lead-free compliance and RoHS adherence. Cross-reference the manufacturer's latest datasheet revision to ensure compatibility with current manufacturing processes and material declarations before finalizing procurement orders.

Selection Notes

Select this component when an extended industrial temperature range up to 125 °C is required alongside low power consumption. The SOT-23 form factor offers space efficiency for dense PCB layouts. Ensure the application can accommodate the shunt configuration and that the 15 mA maximum current rating meets the circuit's load requirements without excessive power dissipation.

Part Context

This part belongs to the LM4040-N/LM4040Q-N family of precision micropower shunt voltage references manufactured by Texas Instruments. The series provides various fixed voltage options in compact packages, designed for applications demanding stability and low power usage. The LM4040EEM3 variant specifically targets high-temperature environments using the SOT-23 footprint.
