Overview
The TLVH431BQLPR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an input voltage range of up 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 temperature coefficient of 138 ppm/°C. It supports a maximum cathode current of 80 mA with a minimum operating current of 80 µA. The component functions reliably across a temperature range of -40°C to +125°C and utilizes a TO-92-3 through-hole package.
Feature Summary
- Provides adjustable reference voltage functionality with high precision for stable regulation.
- Designed for low-voltage applications with extended operational current capabilities.
- Ensures thermal stability over a wide industrial temperature range.
Applications
- Precision voltage references in battery-operated equipment
- Voltage monitoring circuits in data acquisition systems
- Power supply feedback loops in switch-mode power supplies
Procurement Notes
Verify the specific suffix 'BQLPR' against official Texas Instruments documentation to confirm the exact tolerance grade, package type, and environmental compliance status. Ensure that the procurement channel sources genuine components matching the manufacturer's part number specifications to avoid counterfeit risks. Cross-reference the datasheet revision history for any recent changes in electrical characteristics or packaging materials.
Selection Notes
Select this component when a through-hole adjustable shunt regulator with 0.5% accuracy is required for low-voltage designs. Consider the 80 mA sink current capability and 20 V maximum input limit during circuit design. Evaluate the 138 ppm/°C temperature coefficient against system thermal requirements. Compare against other TLVH431 variants if different packages or tighter tolerances are needed.
Part Context
This part belongs to the TLVH431 series of low-voltage adjustable precision shunt regulators from Texas Instruments. The series is designed for space-constrained and power-sensitive applications. The TO-92-3 package variant offers through-hole mounting options suitable for prototyping or specific board layouts requiring mechanical robustness compared to surface-mount alternatives.
Replacement Considerations
Compatible substitutes include TLVH431BQDBVR (SOT-23-5) and TLVH431BILPR (TO-92-3). Verify pinout compatibility and electrical parameter alignment before substitution.
