TLV431ACDBVTG4

Overview

The TLV431ACDBVTG4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an output voltage range of 1.24 V to 18 V and provides an initial accuracy of ±0.5%. The device supports a maximum cathode current of 80 mA and functions with a supply voltage up to 18 V. It is housed in a SOT-23-5 package and is rated for operation between -40°C and +85°C.

Feature Summary

• Adjustable output voltage capability from 1.24 V to 18 V
• High precision with ±0.5% initial accuracy
• Low voltage operation suitable for battery-powered systems

Applications

• Battery-powered equipment
• Portable instruments
• DC/DC converters
• Post-regulators

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the SOT-23-5 package type matches your PCB footprint requirements. Ensure the ±0.5% accuracy grade meets your circuit tolerance specifications before finalizing procurement.

Selection Notes

Select this component when low-voltage precision regulation is required in space-constrained designs. The SOT-23-5 package offers a compact solution compared to traditional TO-92 or DIP packages. Consider the 80 mA cathode current limit for load requirements and verify thermal performance within the specified operating temperature range.

Part Context

This part belongs to the TLV431 family of low-voltage adjustable shunt regulators, designed as drop-in replacements for standard TL431 devices in many applications. The family emphasizes improved performance at lower supply voltages while maintaining high accuracy and stability.

Replacement Considerations

Direct substitutes include the TLV431ACDBVRG4 (same package, different reel packaging) and the TLV431ACDBZTG4 (SOT-23-3 package). Verify pinout compatibility when switching between SOT-23-5 and SOT-23-3 packages.
