TL4050C50QDBZR

Overview

The TL4050C50QDBZRQ1 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 ±0.5% and a temperature coefficient of 50 ppm/°C. The device operates within a junction temperature range of -40°C to +125°C and features a maximum shunt current of 15 mA. It consumes a typical cathode current of 90 µA and exhibits a noise level of 93 µVrms in the 10 Hz to 10 kHz bandwidth. Packaged in a compact SOT-23-3 surface-mount case, it meets AEC-Q100 automotive qualification standards.

Feature Summary

Automotive-grade reliability certified under AEC-Q100 standards for robust performance in vehicle electronics.
Micropower architecture enables low quiescent current consumption suitable for battery-operated systems.
High precision stability maintained through tight initial accuracy and low temperature drift characteristics.

Applications

Automotive sensor signal conditioning circuits
Data acquisition systems requiring stable reference voltages
Portable instrumentation powered by limited energy sources

Procurement Notes

Verify the complete part number includes the Q suffix for automotive qualification status. Confirm the DBZR suffix indicates the specific SOT-23-3 package variant and reel packaging configuration. Ensure compatibility with RoHS3 compliance requirements before integration into final assemblies.

Selection Notes

Select this component when automotive certification is mandatory alongside high precision requirements. The SOT-23-3 package offers space efficiency for dense PCB layouts. Consider the 5 V output level against system rail constraints and verify that the 15 mA load capability meets downstream circuit demands.

Part Context

This device belongs to the TL4050 family of precision voltage references designed for demanding applications. The series combines low power consumption with high accuracy, making it suitable for both industrial and automotive environments where long-term stability and thermal performance are critical design factors.
