TL431AQDBVRQ1

Overview

The TL431AQDBVRQ1 is an adjustable precision shunt regulator from the TL431-Q1 series, designed for automotive applications. It operates within a voltage range of 2.495 V to 36 V and provides an initial accuracy of 1%. The device supports a maximum cathode current of 100 mA and withstands input voltages up to 36 V. It features a temperature coefficient of 92 PPM/°C and functions reliably between -40°C and +125°C. Packaged in a five-pin SOT-23 (DBV) surface-mount case, it meets AEC-Q100 qualification standards.

Feature Summary

AEC-Q100 qualified for automotive reliability
Adjustable output voltage reference
High precision with 1% initial accuracy
Extended industrial temperature range operation

Applications

Automotive power supply regulation
Voltage reference circuits
Linear regulator feedback loops
Battery management systems

Procurement Notes

Verify the specific suffix DBVR indicates the SOT-23-5 package and tape-and-reel shipping configuration. Confirm the 'Q1' designation ensures compliance with AEC-Q100 automotive standards. Check the datasheet for any recent Product Change Notifications regarding marking or material composition updates. Ensure the application circuit accounts for the specified thermal operating limits.

Selection Notes

Select this component when automotive-grade reliability and precise voltage referencing are required in compact designs. The SOT-23-5 package suits space-constrained PCB layouts. Consider the 100 mA current limit for load requirements. Verify that the 36 V maximum input voltage aligns with the system's supply rails. Compare against non-automotive variants if cost sensitivity outweighs qualification needs.

Part Context

This part belongs to the TL431-Q1 family of adjustable precision shunt regulators manufactured by Texas Instruments. These devices serve as versatile references and controllers in power management systems. The Q1 suffix denotes automotive qualification, distinguishing it from commercial grade parts. The family offers various package options including SOT-23 and SOIC formats.
