TL431BIDBZTG4

Overview

The TL431BIDBZTG4 is an adjustable precision shunt regulator manufactured by Texas Instruments, designed for automotive applications. It operates within a reference voltage range of 2.495V to 36V and supports a maximum cathode current of 100mA. The device features an initial accuracy of 0.5% and a maximum temperature coefficient of 92ppm/°C. It is housed in a surface-mount SOT-23 package with three pins and supplied in tape and reel format. The component is rated for operation between 0°C and 70°C, with a maximum input voltage of 37V.

Feature Summary

Provides adjustable precision shunt regulation suitable for automotive environments
Delivers high initial accuracy with low temperature drift characteristics
Utilizes compact surface-mount packaging for automated assembly

Applications

Automotive power supply regulation circuits
Precision voltage reference sources
Feedback control loops in switching regulators

Procurement Notes

Verify the specific suffix 'TG4' confirms the automotive grade and tape-and-reel packaging configuration. Ensure the design accommodates the 0°C to 70°C operating temperature range rather than extended industrial limits. Confirm that the 0.5% initial accuracy meets the system tolerance requirements before finalizing procurement specifications.

Selection Notes

Select this component when automotive qualification and tight initial accuracy are required. Compare against TL431Q variants if extended temperature ranges (-40°C to 125°C) are necessary, noting the trade-off in accuracy. Ensure the circuit design supports the minimum cathode current requirement for stable regulation during light load conditions.

Part Context

This part belongs to the TL431 family of adjustable shunt regulators from Texas Instruments. It shares functional similarities with other TL431 variants but is distinguished by its automotive grade designation and specific accuracy class. The device serves as a fundamental building block for voltage monitoring and regulation tasks in electronic systems.

Replacement Considerations

Direct substitutes include TL431BCDBZTG4 for similar automotive performance or TL431BQDBZTG4 for extended temperature operation. Verify pin compatibility and thermal characteristics when transitioning between these variants.
