TL431AQDBZR

Overview

The TL431AQDBZR is an adjustable precision shunt regulator manufactured by Texas Instruments, housed in a SOT-23-3 surface-mount package. It operates within a voltage range of 2.495V to 36V with an initial accuracy of ±1%. The device supports a maximum cathode current of 100mA and a minimum operating current of 600µA. It features a temperature coefficient of 92ppm/°C and functions across an extended industrial temperature range from -40°C to +125°C. This component complies with AEC-Q100 automotive standards.

Feature Summary

Provides adjustable reference voltage output via external resistors
Delivers high initial accuracy for precise regulation
Complies with AEC-Q100 automotive qualification standards

Applications

Automotive power supply regulation circuits
Precision voltage reference sources
Programmable output control loops

Procurement Notes

Verify the specific suffix 'Q' confirms AEC-Q100 automotive qualification status against official datasheets. Confirm the 'DBZR' suffix indicates the SOT-23-3 package and reel packaging type. Ensure compatibility with required thermal management specifications for the intended operating environment.

Selection Notes

Select this component when automotive-grade reliability and high precision are required. The wide operating temperature range suits harsh environments. Consider the low minimum cathode current for efficient light-load performance. Verify that the SOT-23-3 package fits the PCB layout constraints.

Part Context

This part belongs to the TL431 family of programmable shunt regulators. It serves as a three-terminal reference diode equivalent, offering superior performance over standard Zener diodes. The device is widely used in feedback networks for switching power supplies and linear regulators requiring stable reference voltages.
