LM4040EIM3X-3.0/NOPB

Overview

The LM4040EIM3X-3.0/NOPB is a precision 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 ±0.2%. The device features a temperature coefficient of 150 ppm/°C and supports a maximum cathode current of 15 mA. Designed for surface-mount applications, it operates within a temperature range of -40°C to +85°C.

Feature Summary

Provides stable 3.0 V reference voltage with high precision
Micropower operation suitable for battery-powered systems
Compact SOT-23 surface-mount packaging

Applications

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

Procurement Notes

Verify the specific suffix 'E' against official Texas Instruments documentation to confirm grade and availability status. Ensure the ordering part number matches the exact tolerance and temperature coefficient requirements for the target application. Cross-reference with the latest datasheet revision to confirm RoHS compliance and package details before finalizing procurement.

Selection Notes

Select this component when a 3.0 V fixed reference with ±0.2% initial accuracy is required. The 150 ppm/°C temperature coefficient defines its thermal stability limits. Consider the 15 mA maximum cathode current for load regulation capabilities. Verify that the SOT-23 footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the LM4040-N series of micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades. The 'E' designation typically indicates a specific performance bin or grade within the product family, while 'NOPB' denotes lead-free construction.

Replacement Considerations

LM4040BIM3X-3.0/NOPB: Offers similar form factor but may differ in temperature coefficient (150 ppm/°C vs 100 ppm/°C for E-grade) and initial accuracy specifications. Verify electrical parameters match application needs.
