Overview
The TLV431ACDBVRE4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an output voltage range of 1.24 V to 6 V and supports a maximum cathode current of 15 mA. The device features an initial accuracy of ±1% and a temperature coefficient of 138 ppm/°C. Designed for surface-mount applications, it utilizes a 3-pin SOT-23 package. The component functions effectively across a temperature range of 0°C to 70°C, providing stable reference performance for compact electronic designs.
Feature Summary
- Provides precise adjustable voltage referencing with high initial accuracy
- Operates efficiently at low voltages suitable for portable electronics
- Utilizes a compact three-terminal surface-mount package design
Applications
- Portable equipment power supply regulation
- DC-to-DC converter feedback loops
- Battery-powered system voltage monitoring
Procurement Notes
Verify the specific suffix E4 indicates lead-free compliance when sourcing. Confirm the package type matches the required PCB footprint. Ensure the operating environment stays within the specified thermal limits. Cross-reference the manufacturer part number against authorized distributors to avoid counterfeit components. Check for any recent production change notices affecting specifications.
Selection Notes
Select this component when low-voltage operation and tight accuracy are required in a small form factor. Compare the 15 mA current limit against circuit demands to ensure adequate drive capability. Evaluate the temperature coefficient requirements against the application's thermal conditions. Consider the SOT-23 package constraints for board space limitations.
Part Context
This device belongs to the TLV431 family of low-voltage adjustable shunt regulators. It serves as a modern alternative to traditional Zener diodes, offering superior stability and lower noise. The family is widely used in power management circuits where precise voltage control is essential for system reliability and efficiency.
Replacement Considerations
Direct substitutes include the TLV431ACDBZR and TLV431ACDBZRG4. Verify pinout compatibility and electrical parameters before substitution. Ensure the replacement maintains the same accuracy and current handling capabilities.
