TL431QDBZR

Overview

The TL431QDBZR is an adjustable precision shunt regulator from Texas Instruments, designed for automotive and industrial applications. It operates within a voltage range of 2.495V to 36V with an initial accuracy of ±2.2%. The device features a maximum cathode current of 100mA and a low operating current of 1μA. It is housed in a SOT-23-3 package and supports a wide operating temperature range from -40°C to +125°C.

Feature Summary

Adjustable output voltage ranging from 2.495V to 36V via external resistors
Low operating current of 1μA suitable for power-sensitive designs
Automotive qualification compliant with AEC-Q100 standards

Applications

Automotive power supply regulation
Linear regulator feedback loops
Motor control circuit references

Procurement Notes

Verify the specific suffix 'Q' indicates automotive grade qualification and AEC-Q100 compliance. Confirm the package type is SOT-23-3 and check for RoHS status. Ensure the initial accuracy specification matches the required design tolerance of ±2.2% before procurement.

Selection Notes

Select this component when automotive reliability and low quiescent current are critical. The SOT-23-3 package offers space efficiency. Compare against standard TL431 variants if higher accuracy or different temperature ranges are needed. Verify input voltage limits do not exceed 36V in the target application.

Part Context

This part belongs to the TL431 family of programmable shunt regulators. It serves as a cost-effective reference voltage source. The Q-series designation typically denotes automotive-grade manufacturing processes and enhanced reliability testing compared to commercial variants.

Replacement Considerations

Compatible substitutes include TL431AQDBZR and ATL431AIDBZR. Verify pinout compatibility and electrical specifications such as initial accuracy and operating temperature range before substitution.
