LM4040DIM3-2.5-TR

Overview

The LM4040DIM3-2.5-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 output voltage of 2.5V with an initial accuracy tolerance of ±1%. The device operates within a temperature range of -40°C to +85°C and features a maximum average temperature coefficient of 150 ppm/°C. Electrical characteristics include a minimum operating current of 65 µA and a maximum operating current of 15 mA.

Feature Summary

Bandgap reference architecture with temperature drift curvature correction for stable voltage accuracy across wide operating conditions.
Capable of tolerating capacitive loads without requiring an external output capacitor for stability.
Low dynamic impedance ensures consistent performance under varying load currents.

Applications

Battery-powered equipment
Data acquisition systems
Instrumentation
Process control

Procurement Notes

Verify the specific D-grade accuracy and 150 ppm/°C temperature coefficient against design requirements. Confirm that the SOT-23 package orientation matches the schematic pinout. Ensure the supply voltage and series resistor values maintain the operating current between 65 µA and 15 mA.

Selection Notes

Select this component when space constraints necessitate a subminiature SOT-23 footprint. Choose this part over higher precision grades if the ±1% tolerance and 150 ppm/°C drift are acceptable for the application's accuracy needs.

Part Context

This device belongs to the LM4040/LM4041 family of precision micropower shunt voltage references. The LM4040 variant offers fixed output voltages, while the LM4041 includes adjustable versions. Both families share similar low-power characteristics and compact packaging options designed for portable and space-critical electronics.
