LM4040BIM3X-2.5/NOPB

Overview

The LM4040BIM3X-2.5/NOPB is a precision micropower shunt voltage reference from Texas Instruments, housed in a compact SOT-23-3 surface-mount package. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.2%. The device operates within a temperature range of -40°C to +85°C and features a maximum shunt current of 15 mA. Designed for low-power applications, it draws a typical quiescent current of 70 µA.

Feature Summary

Provides stable reference voltage with high initial accuracy
Operates at micropower levels suitable for battery systems
Compact three-terminal surface-mount design

Applications

Portable instrumentation circuits
Battery-powered measurement devices
Data acquisition systems requiring precise voltage references

Procurement Notes

Verify the complete part number including suffixes such as NOPB and X to ensure correct packaging and lead-free compliance. Confirm that the specific accuracy grade matches the design requirements before procurement. Check for RoHS compliance status if environmental regulations apply to the manufacturing process.

Selection Notes

Select this component when a fixed 2.5 V reference is required with tight tolerance specifications. Ensure the application circuit can maintain the minimum operating current while staying below the maximum shunt current limit. Consider the thermal environment to ensure operation remains within the specified industrial temperature range.

Part Context

This device belongs to the LM4040 series of precision shunt voltage references. The series offers various fixed voltage options and accuracy grades. The LM4040 family is designed to replace larger Zener diodes in space-constrained designs while providing superior stability and lower noise characteristics compared to standard references.
