TLV431BQDBVR

Overview

The TLV431BQDBVR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an output voltage range of 1.24 V to 6 V and provides an initial accuracy of ±0.5%. The device supports a maximum cathode current of 15 mA with a minimum operating current of 100 µA. It features a temperature coefficient of 138 ppm/°C and withstands a maximum series input voltage of 7 V. The component functions across a wide ambient temperature range from -40°C to +125°C and is housed in a surface-mount SOT-23-5 package.

Feature Summary

Provides adjustable reference voltage functionality using external resistors
Delivers high initial accuracy for precise voltage regulation applications
Operates reliably across extended industrial temperature ranges

Applications

Battery-powered equipment requiring stable reference voltages
DC-to-DC converter feedback loops
Portable instrumentation circuits

Procurement Notes

Verify the specific suffix 'B' indicates the required ±0.5% accuracy grade, as other variants exist. Confirm the 'Q' designation aligns with your quality standards, though this part is not AEC-Q100 qualified unlike the Q1 variant. Ensure the SOT-23-5 footprint matches your PCB layout constraints before ordering.

Selection Notes

Select this component when a compact, low-cost adjustable reference is needed for general-purpose power management. It is suitable for applications where ±0.5% accuracy suffices and does not require automotive qualification. Consider the TLV431BQDBVRQ1 if automotive reliability standards are mandatory for the end product.

Part Context

This device belongs to the TLV431 family of low-voltage adjustable precision shunt regulators. It serves as a cost-effective alternative to traditional Zener diodes, offering superior stability and lower temperature coefficients. The standard TLV431BQDBVR is designed for commercial and industrial use, distinct from the automotive-grade Q1 version.
