TLVH431BCDBVRG4

Overview

The TLVH431BCDBVRG4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 20 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features an initial accuracy of ±0.5% and a maximum cathode current of 80 mA. It functions over an extended temperature range from -40°C to +125°C. The component is housed in a five-pin SOT-23 package (LSSOP, TSOP5/6,.11,37) and complies with RoHS standards.

Feature Summary

• Provides precise voltage regulation with ±0.5% initial accuracy for stable reference applications
• Supports wide operating voltage ranges up to 20 V with adjustable output capabilities
• Designed for high thermal stability across industrial temperature extremes

Applications

• Precision voltage references in battery-powered equipment
• Programmable power supplies requiring accurate shunt regulation
• Voltage monitoring circuits in automotive or industrial systems

Procurement Notes

Verify the specific suffix G4 indicates lead-free and RoHS compliance status against the latest manufacturer documentation. Confirm the SOT-23-5 pinout matches your PCB footprint requirements. Check for any recent lifecycle notices regarding obsolescence or recommended replacements. Ensure the operating temperature range meets your environmental specifications. Validate that the 80 mA cathode current capability satisfies your circuit load demands.

Selection Notes

Select this component when high accuracy is required alongside low voltage operation. Compare the 80 mA cathode current limit against other series variants like the TLVH431A if higher current is needed. Consider the SOT-23-5 package size constraints relative to available board space. Evaluate the ±0.5% tolerance against less precise alternatives if cost reduction is prioritized over performance.

Part Context

This part belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators. It serves as a three-terminal voltage reference suitable for replacing standard Zener diodes in many applications. The device integrates a bandgap reference and error amplifier to maintain stable output voltages under varying load conditions.

Replacement Considerations

Check for direct equivalents such as the TLVH431BCDBVTE4. Verify pin compatibility and electrical parameter alignment before substitution.
