TLVH431ACLP

Overview

The TLVH431ACLP 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 1% and a maximum temperature coefficient of 138 ppm/°C. It supports a maximum shunt current of 80 mA with a minimum operating current of 80 µA. The component functions across a wide temperature range from -40°C to +125°C and is housed in a TO-92-3 through-hole package.

Feature Summary

• Adjustable output voltage set via external resistor divider
• Guaranteed temperature stability over the entire operating range
• Low operating current suitable for power-restricted designs
• High sink current capability for precise regulation

Applications

• Battery chargers
• Switch mode power supplies
• Battery operated equipment
• Data acquisition systems
• Energy management circuits

Procurement Notes

Verify the specific suffix 'CLP' against the official Texas Instruments datasheet to confirm the exact package variant and tape/reel specifications. Ensure the selected part matches the required thermal performance and accuracy grade for your design. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when a through-hole TO-92 package is required for low-voltage precision reference applications. It is suitable for designs needing high sink current capability and wide temperature operation. Compare its 138 ppm/°C temperature coefficient against stricter requirements if higher precision is needed. Consider surface-mount alternatives like SOT-23 if board space is limited.

Part Context

This part belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators. It serves as a drop-in replacement for standard TL431 devices in many low-voltage applications but offers improved performance at lower supply voltages. The family includes various packages and accuracy grades to support diverse industrial and consumer electronics needs.

Replacement Considerations

Publicly confirmed substitute part numbers include TLVH431ACLPR and TLVH431ACLPWR. Verify pinout compatibility and electrical parameters such as maximum input voltage and shunt current when substituting.
