LM4040CIM3-2.5-TR

Overview

The LM4040CIM3-2.5-TR is a precision micropower shunt voltage reference manufactured by Microchip Technology, housed in a 3-pin SOT-23 surface-mount package. It provides a fixed reverse-breakdown voltage of 2.500V with an initial tolerance of ±1% and a maximum temperature coefficient of 100 ppm/°C. The device operates within a temperature range of -40°C to +85°C, drawing a minimum current of 60 µA and supporting a maximum operating current of 15 mA.

Feature Summary

Bandgap reference curvature correction for stable accuracy across wide temperature and current ranges
Capable of tolerating capacitive loads without requiring output capacitors
Low dynamic impedance ensures consistent performance under varying load conditions

Applications

Battery-powered equipment
Data acquisition systems
Instrumentation
Process control
Precision audio components

Procurement Notes

Verify the specific suffix '-TR' indicates tape-and-reel packaging when sourcing from distributors. Confirm that the 'C' grade designation aligns with the required ±1% initial tolerance and 100 ppm/°C temperature coefficient specifications. Ensure the ordering part number matches the exact manufacturer prefix for Microchip Technology to avoid cross-manufacturer discrepancies.

Selection Notes

Select this component for applications requiring a compact footprint due to the subminiature SOT-23 package. It is suitable for designs needing a fixed 2.5V reference with micropower consumption characteristics. Consider the 15 mA maximum current limit when designing the series resistor network for shunt regulator configurations.

Part Context

This device belongs to the LM4040/LM4041 family of precision micropower shunt voltage references. The LM4040 variant specifically offers fixed breakdown voltages, distinguishing it from the adjustable LM4041 version. Both families share similar low-noise and high-stability features designed for space-critical electronic applications.
