TL4050C50QDBZT

Overview

The TL4050C50QDBZT 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%. The device features a low 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 +125°C and is housed in a SOT-23-3 surface-mount package. The component holds AEC-Q100 qualification for automotive applications.

Feature Summary

• AEC-Q100 qualified for automotive reliability standards
• Precision micropower shunt architecture
• Low temperature coefficient for thermal stability

Applications

• Automotive data acquisition systems
• Portable instrumentation
• Battery-powered measurement devices

Procurement Notes

Verify the specific suffix 'DBZT' against the official datasheet to confirm the tape-and-reel packaging configuration, as distributor listings may vary between cut tape and reel formats. Ensure the part number matches the exact tolerance grade and temperature rating required for the target application environment.

Selection Notes

Select this component when a stable 5 V reference is needed in space-constrained designs requiring automotive-grade reliability. Compare its 50 PPM/°C drift against higher precision alternatives if tighter thermal stability is required. Verify that the 15 mA maximum shunt current meets the load requirements of the downstream circuitry.

Part Context

This part belongs to the TL4050-Q1 family of precision voltage references designed for harsh environments. It shares the core performance characteristics of the series but is distinguished by its specific 5 V output voltage and ±0.5% initial accuracy grade within the SOT-23-3 package form factor.

Replacement Considerations

LM4040C50QDBZT offers similar functionality but with a higher temperature coefficient of 150 PPM/°C.
