Overview
The TLVH431ACDBVR 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 supports a maximum cathode current of 80 mA. The device features an initial accuracy of 0.5% and a temperature coefficient of 138 ppm/°C. It is housed in a five-pin SOT-23 surface-mount package and is designed for operation across a temperature range of -40°C to +125°C.
Feature Summary
- Provides precise voltage regulation with high initial accuracy suitable for demanding applications
- Operates efficiently at low voltages, enabling extended battery life in portable devices
- Features a compact surface-mount footprint optimized for space-constrained circuit designs
Applications
- Battery-powered equipment requiring stable reference voltages
- Portable consumer electronics with limited power budgets
- Industrial control systems utilizing programmable power supplies
Procurement Notes
Verify the specific suffix 'ACDBVR' against official Texas Instruments documentation to confirm the exact accuracy grade and packaging configuration. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.
Selection Notes
Select this component when low-voltage operation and tight accuracy are required. Compare the 0.5% initial accuracy against standard variants if cost sensitivity is higher. Confirm that the SOT-23-5 package meets the spatial constraints of the target design.
Part Context
This part belongs to the TLVH431 family of low-voltage shunt regulators. It serves as a drop-in replacement for traditional TL431 devices in low-voltage applications, offering improved performance at reduced supply voltages while maintaining similar pin configurations.
Replacement Considerations
Direct substitutes include other TLVH431 variants with different accuracy grades or packages, such as TLVH431BCDBVR. Verify electrical parameters match the original design requirements before substitution.
