TL431IDBZTG4

Overview

The TL431IDBZTG4 is a precision programmable shunt regulator manufactured by Texas Instruments. It operates as a three-terminal voltage reference with an adjustable output range from 2.495 V to 36 V. The device features an initial accuracy of 0.5% and supports a maximum cathode current of 100 mA. It is housed in a surface-mount SOT-23 package and is rated for operation within a temperature range of -40 °C to +85 °C.

Feature Summary

Provides precise voltage regulation through external resistor programming
Ensures stable performance with low dynamic impedance characteristics
Offers high thermal stability across the specified industrial temperature range

Applications

Precision voltage references in power supply circuits
Programmable output regulators for DC-DC converters
Error amplifiers in feedback control loops

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status according to the manufacturer's latest documentation. Confirm the package marking and pinout configuration match the SOT-23 standard before integration. Ensure the ordering part number matches the required accuracy grade and temperature rating for the target application environment.

Selection Notes

Select this component when a 0.5% initial accuracy is required for voltage referencing applications. It is suitable for designs needing an adjustable output up to 36 V with a compact SOT-23 footprint. Consider the -40 °C to +85 °C operating range to ensure compatibility with industrial environmental conditions and thermal management requirements.

Part Context

This device belongs to the TL431 family of adjustable precision shunt regulators. It serves as a direct replacement for legacy TL431 variants while offering improved accuracy and modern packaging options. The component is widely used in analog circuit design for providing stable reference voltages and regulating output levels in various power management topologies.
