LM4040C25IDCKR

Overview

The LM4040C25IDCKR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.5%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 100 ppm/°C. Electrical specifications include a maximum shunt current of 15 mA and a minimum cathode current of 75 µA. It is housed in a compact SC-70-5 surface-mount package, suitable for space-constrained designs requiring stable voltage references.

Feature Summary

Provides a fixed 2.5 V reference output with high precision
Operates as a shunt regulator with low power consumption
Designed for surface-mount applications in small packages

Applications

Portable battery-powered equipment
Data acquisition systems
Handheld instruments

Procurement Notes

Verify the specific suffix IDCKR corresponds to the SC-70-5 package and standard commercial grade (C) when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the component is sourced from verified channels to avoid counterfeit parts, as availability may vary across regions.

Selection Notes

Select this component when a fixed 2.5 V reference is required in a small surface-mount footprint. It is suitable for applications needing ±0.5% accuracy and operation up to 85°C. Consider thermal management if operating near maximum current limits. Verify that the SC-70-5 package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references. The 'C' indicates a commercial temperature range (-40°C to +85°C), while '25' denotes the 2.5 V output voltage. The 'IDCKR' suffix specifies the SC-70-5 package and reel packaging. This series offers alternatives to larger packages like SOT-23-3 or TO-92 for different size requirements.
