Overview
The TLVH431BILP 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 with an initial accuracy of ±0.5%. The device supports a maximum cathode current of 70 mA and features a temperature coefficient of 161 PPM/°C. It functions with a minimum operating current of 100 µA and withstands a maximum reference-to-cathode voltage of 20 V. The component is designed for surface-mount installation in SOT-23-3 packages, ensuring stable performance across industrial temperature ranges.
Feature Summary
- Provides adjustable output voltage capability via external resistor dividers
- Ensures high precision with guaranteed initial accuracy specifications
- Maintains stability over wide operating temperature conditions
Applications
- Battery chargers
- Switch mode power supplies
- Data acquisition systems
Procurement Notes
Verify the specific suffix against official Texas Instruments documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for SOT-23-3 or TO-92 variants depending on the exact sub-model. Confirm RoHS compliance status through the manufacturer's latest release notes before integration into production designs.
Selection Notes
Select this component when precise voltage referencing is required in space-constrained designs. The low operating current makes it suitable for battery-powered applications where power efficiency is critical. Verify that the required sink current does not exceed the specified maximum limits for the chosen thermal environment.
Part Context
This part belongs to the TLVH431 series of three-terminal voltage references. The series offers various accuracy grades and package options to suit different design constraints. It serves as a drop-in replacement for traditional Zener diodes in regulation and reference circuits, providing superior temperature stability and lower dynamic impedance compared to discrete alternatives.
Replacement Considerations
Check for direct equivalents such as TLVH431AILP or TLVH431CILP if different accuracy grades are acceptable. Verify pinout compatibility with legacy components like TL431 before substitution.
