TL4051BQDBZR

Overview

The TL4051BQDBZR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It operates within an input voltage range of up to 15 V and provides fixed output voltages between 1.212 V and 10 V. The device features an initial accuracy of 0.2% and a temperature coefficient of 50 ppm/°C. Maximum shunt current is 15 mA, with a cathode current of 90 µA. It functions in temperatures from -40°C to +125°C and is housed in an SOT-23-3 package.

Feature Summary

Provides high-precision voltage referencing with 0.2% initial accuracy
Operates as a micropower shunt regulator with low cathode current
Designed for automotive applications with AEC-Q100 qualification

Applications

Automotive data acquisition systems
Precision analog-to-digital converter references
Battery-powered instrumentation circuits

Procurement Notes

Verify the specific output voltage variant required, as the TL4051B series covers multiple fixed voltage options. Confirm that the SOT-23-3 package aligns with the PCB footprint. Ensure the design supports the maximum shunt current limits under all operating conditions. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when automotive-grade reliability and tight initial accuracy are required. The 50 ppm/°C temperature coefficient suits applications with moderate thermal variations. Compare against the TL4051A series if higher precision (0.1%) is needed, or the TL4050 series for different noise characteristics. Ensure the input voltage remains within the specified maximum limit during operation.

Part Context

This part belongs to the TL4051 family of precision shunt voltage references. It shares the SOT-23-3 form factor with other variants in the series but differs in initial accuracy and temperature coefficient specifications. The 'Q' suffix indicates automotive qualification, distinguishing it from standard commercial grade devices.
