TL4050B50IDCKR

Overview

The TL4050B50IDCKR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 5 V with an initial accuracy of ±0.2%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 50 ppm/°C. It is housed in a SC-70-5 surface-mount package and supports a maximum cathode current of 15 mA.

Feature Summary

• Provides stable 5 V reference output with high initial accuracy
• Designed for low power consumption applications
• Operates reliably across extended industrial temperature ranges

Applications

• Portable instrumentation requiring precise voltage references
• Battery-powered measurement systems
• Data acquisition circuits

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 before integration. Ensure ordering quantities align with standard reel packaging requirements specified by the supplier.

Selection Notes

Select this component when a 5 V fixed reference with ±0.2% accuracy is required in a compact SC-70-5 footprint. It is suitable for designs prioritizing low quiescent current and moderate precision over ultra-low noise specifications found in higher-tier series.

Part Context

This part belongs to the TL4050 family of precision shunt voltage references from Texas Instruments. The family offers various fixed output voltages and accuracy grades, utilizing a common underlying architecture optimized for space-constrained, battery-operated electronic devices requiring reliable voltage regulation.

Replacement Considerations

Check for direct pin-compatible alternatives within the same TL4050 series offering different voltage outputs or accuracy grades. Verify thermal performance and package dimensions against existing board layouts before substitution.
