TL4050A50QDCKT

Overview

The TL4050A50QDCKT 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 0.1% and a temperature coefficient of 30 PPM/C. The device operates within a junction temperature range of -40°C to +125°C and supports a maximum shunt current of 15 mA. Packaged in a compact SC70-5 surface-mount case, it is designed for space-constrained applications requiring high stability.

Feature Summary

• Delivers high-precision voltage regulation with tight initial accuracy tolerances suitable for sensitive measurement circuits.
• Engineered for low power consumption through micropower operation characteristics ideal for battery-powered systems.
• Features robust thermal stability across extended industrial temperature ranges to maintain performance consistency.

Applications

• Portable instrumentation requiring stable reference voltages
• Battery-operated data acquisition systems
• Precision analog-to-digital converter references

Procurement Notes

Verify the specific suffix QDCKT against the official datasheet to confirm automotive qualification status and package variant. Ensure compatibility with existing PCB footprints for the SC70-5 package. Confirm end-of-life or obsolescence status directly with the manufacturer before finalizing design-in decisions.

Selection Notes

Select this component when strict accuracy requirements of 0.1% are necessary alongside low power constraints. Compare temperature coefficients against application thermal profiles. Evaluate the SC70-5 footprint availability against alternative packages if board space permits other form factors.
