LM4040CYM3-2.5-TR

Overview

The LM4040CYM3-2.5-TR is a precision micropower shunt voltage reference manufactured by Microchip Technology, housed in a subminiature SOT-23 surface-mount package. It provides a fixed reverse-breakdown output voltage of 2.500V with an initial accuracy tolerance of ±0.5%. The device operates within a temperature range of -40°C to +85°C and features a maximum average temperature coefficient of 100 ppm/°C. Electrical characteristics include a typical wideband noise of 35 µVrms and a minimum operating current of 60 µA.

Feature Summary

Bandgap reference architecture with curvature correction for stable voltage accuracy across varying temperatures and currents
Capable of tolerating capacitive loads without requiring an external output capacitor
Low dynamic impedance ensures consistent performance under changing load conditions

Applications

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

Procurement Notes

Verify the specific C-grade designation and 2.5V output configuration against the official datasheet specifications. Confirm that the TR suffix indicates tape-and-reel packaging compatible with automated assembly processes. Ensure the component meets RoHS compliance requirements for the target market.

Selection Notes

Select this component when space constraints necessitate a small SOT-23 footprint while maintaining high precision. It is suitable for applications requiring low quiescent current operation down to 60 µA. Consider the 100 ppm/°C temperature coefficient limit when designing for environments with significant thermal variations.

Part Context

This part belongs to the LM4040/LM4041 family of precision micropower shunt voltage references. The LM4040 series specifically offers fixed voltage options including 2.5V, 4.096V, and 5.0V. The CYM3 suffix denotes the C-grade accuracy level and the SOT-23 package type.
