TL4050B25IDCKR

Overview

The TL4050B25IDCKR 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 ±0.2%. The device features a temperature coefficient of 50 PPM/°C and supports a maximum shunt current of 15 mA. It operates within a temperature range of -40°C to +85°C. The component is housed in a compact SC-70-5 surface-mount package, designed for space-constrained applications requiring stable voltage regulation.

Feature Summary

• Provides precise fixed voltage regulation suitable for sensitive analog circuits
• Operates efficiently with low quiescent current consumption
• Maintains stability across a wide industrial temperature range

Applications

• Portable battery-powered instrumentation
• Data acquisition systems
• Handheld meters

Procurement Notes

Verify the specific suffix IDCKR corresponds to the SC-70-5 package and standard operating temperature range. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ordering quantities align with reel specifications if applicable.

Selection Notes

Select this component when a 2.5 V reference with ±0.2% accuracy is required in a small footprint. Compare against higher accuracy grades or automotive qualified variants if environmental conditions exceed standard industrial limits. Verify input voltage requirements remain within specified operational boundaries.

Part Context

This part belongs to the TL4050 family of precision shunt references from Texas Instruments. The 'B' designation indicates a specific accuracy grade of ±0.2%, while '25' denotes the 2.5 V output. The 'IDCKR' suffix specifies the SC-70-5 package and tape-and-reel packaging format for automated assembly processes.

Replacement Considerations

TL4050B25IDCKRG4 is a verified equivalent variant within the same product line.
