LM4040EIM3-3.0/NOPB

Overview

The LM4040EIM3-3.0/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, housed in a compact SOT-23 package. It provides a fixed nominal output voltage of 3.0 V with an initial accuracy of ±0.5%. The device exhibits a temperature coefficient of 100 ppm/°C, ensuring stable performance across the industrial operating temperature range of -40°C to +85°C. It operates with a minimum cathode current of 67 µA and supports a maximum shunt current of 15 mA.

Feature Summary

Micropower operation with low quiescent current consumption suitable for battery-powered systems
High precision stability with a temperature coefficient of 100 ppm/°C
Compact surface-mount SOT-23 packaging for space-constrained designs

Applications

Portable instrumentation requiring precise voltage references
Battery-operated measurement devices
Data acquisition systems needing stable analog references

Procurement Notes

Verify the specific suffix 'E' indicates the ±0.5% accuracy grade and 'M3' denotes the SOT-23 package configuration. Confirm the 'NOPB' suffix ensures lead-free and RoHS compliance as per manufacturer specifications. Cross-reference the full part number against official Texas Instruments documentation to ensure compatibility with design requirements before procurement.

Selection Notes

Select this component when a fixed 3.0 V reference with 100 ppm/°C drift is required in a small footprint. It is appropriate for applications where power efficiency is critical due to its micropower characteristics. Ensure the load current remains within the specified 67 µA minimum and 15 mA maximum limits for proper regulation.

Part Context

This device belongs to the LM4040-N series of precision micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades, all sharing the same low-power architecture and SOT-23 form factor. It serves as a standard reference solution for general-purpose analog circuits requiring stable voltage levels.
