LM4040BIM3-2.5-T

Overview

The LM4040BIM3-2.5-T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc. under the Maxim Integrated brand. 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 temperature coefficient of 100 PPM/°C. Designed for surface-mount applications, it utilizes a SOT-23-3 package. The component supports a cathode current range from a minimum of 60 µA to a maximum of 15 mA.

Feature Summary

Bandgap reference technology with curvature correction for stable performance across operating temperatures
Low dynamic impedance ensuring accurate reverse breakdown voltage stability
Capacitive load tolerance without requiring external output capacitors

Applications

Space-critical surface-mount designs due to subminiature packaging
Portable battery-powered instrumentation requiring low quiescent current
Precision analog-to-digital converter (ADC) reference sources
Data acquisition systems requiring stable voltage benchmarks

Procurement Notes

Verify manufacturer attribution carefully as this part number appears in listings associated with both Analog Devices/Maxim Integrated and Texas Instruments. Confirm RoHS compliance status through official documentation before integration. Ensure the specific suffix matches the required reel or cut tape configuration for your assembly line. Validate that the source distributor provides traceable origin data for quality assurance purposes.

Selection Notes

Select this component when a 2.5 V reference with ±0.2% initial accuracy is required in a compact SOT-23 form factor. It is suitable for applications needing operation down to 60 µA cathode current. Consider alternative grades if tighter initial tolerance or lower temperature coefficients are necessary for the specific design constraints.

Part Context

This device belongs to the LM4040 series of precision micropower shunt voltage references. The series is characterized by its small physical footprint and ability to tolerate capacitive loads. It serves as a direct replacement for legacy discrete zener diodes in circuits demanding higher stability and lower noise profiles over varying temperature conditions.
