TLA431AIDBZR

Overview

The TLA431AIDBZR is a precision programmable shunt voltage reference manufactured by Texas Instruments. It operates within an output voltage range of 2.5 V to 36 V and features an initial accuracy of ±1%. The device has a temperature coefficient of 48 ppm/°C and supports a maximum cathode current of 100 mA. It functions with an input voltage range from 2.47 V to 36 V. The component is housed in a SOT-23-3 surface-mount package and is rated for operation between -40°C and +85°C.

Feature Summary

Adjustable precision shunt regulation capability
All-capacitor stable design without external compensation requirements
Surface-mount packaging for compact board integration

Applications

Secondary side regulation in flyback switch-mode power supplies
Adjustable voltage and current references
Zener diode replacement applications
Voltage monitoring circuits

Procurement Notes

Verify the exact part number against official Texas Instruments documentation, as similar identifiers like ATL431 or TLV431 exist with different electrical characteristics. Confirm that the specific suffix matches the required tolerance and package type. Ensure compatibility with the intended thermal environment and current requirements before finalizing procurement decisions.

Selection Notes

Select this component when a standard 36 V adjustable reference with ±1% accuracy is required. It serves as a direct alternative to legacy TL431 devices where all-capacitor stability is necessary. Consider the SOT-23-3 footprint constraints and the operating temperature range limits during circuit design to ensure reliable performance under specified conditions.

Part Context

This device belongs to the TLA431 series of programmable references. It shares functional similarities with the broader TL431 family but offers specific stability improvements allowing capacitor-only usage. The TLA431AIDBZR variant specifically denotes the A-grade accuracy and DBZR SOT-23-3 tape-and-reel packaging configuration.
