TL431IDBVRG4

Overview

The TL431IDBVRG4 is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.495 V to 36 V and features an initial accuracy of ±2.2%. The device has a maximum cathode current of 100 mA and a typical temperature coefficient of 92 PPM/°C. It functions in a surface-mount SOT-23-5 package with an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides stable reference voltage through adjustable shunt regulation
• Ensures precise output stability with specified initial accuracy
• Supports wide input voltage operation up to 36 V

Applications

• Precision voltage references in power supply circuits
• On-line isolation amplifiers
• Operational amplifier support circuits

Procurement Notes

Verify the complete part number including the G4 suffix to confirm lead-free compliance and specific manufacturing revision. Confirm the SOT-23-5 package type matches the design footprint. Ensure the ±2.2% accuracy specification meets the system requirements for the intended application environment.

Selection Notes

Select this component when a low-cost, high-accuracy adjustable reference is required in a compact surface-mount package. The ±2.2% tolerance offers better precision than standard variants while maintaining compatibility with common TL431 footprints. Consider the thermal performance within the specified industrial temperature range during circuit layout.

Part Context

This device belongs to the TL431 family of programmable shunt regulators. It serves as a direct replacement for legacy TL431 components in existing designs. The G4 suffix indicates a lead-free and RoHS-compliant version produced by Texas Instruments, ensuring environmental compliance for modern electronics manufacturing.

Replacement Considerations

Compatible substitutes include TL431IDBVR and TL431IDBVT. Verify pinout compatibility and electrical specifications before substitution.
