TL4050B50QDCKT

Overview

The TL4050B50QDCKT is a micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 5V with an initial accuracy tolerance of ±0.2%. The device features a temperature coefficient of 50ppm/°C and operates within a junction temperature range of -40°C to +125°C. It supports a maximum cathode current of 15mA and draws a typical quiescent current of 90µA. The component is housed in a SC-70-5 surface-mount package and meets AEC-Q100 automotive qualification standards.

Feature Summary

Automotive-grade reliability certified under the AEC-Q100 standard for robust performance in vehicle electronics.
Micropower architecture designed for minimal energy consumption, suitable for battery-powered systems.
High precision voltage regulation with tight initial accuracy and low temperature drift characteristics.

Applications

Automotive sensor signal conditioning circuits
Portable medical instrumentation requiring stable reference voltages
Data acquisition systems needing high-accuracy analog-to-digital conversion references

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure correct packaging and automotive grade specifications. Confirm availability status as distribution channels may vary. Cross-reference pinouts and thermal characteristics with the latest datasheet before finalizing procurement decisions.

Selection Notes

Select this component when automotive qualification is mandatory alongside precise voltage referencing. Compare the 50ppm/°C temperature coefficient against application thermal requirements. Evaluate the SC-70-5 footprint constraints against PCB layout limitations. Ensure the 15mA load capability matches the downstream circuit demands.

Part Context

This part belongs to the TL4050 series of precision micropower shunt voltage references from Texas Instruments. The series offers various output voltages and accuracy grades tailored for industrial and automotive applications. The B grade indicates a tighter tolerance band compared to standard commercial variants, ensuring enhanced stability across operating conditions.
