TLV431ACLP

Overview

The TLV431ACLP is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an input voltage range of up to 7 V and supports an adjustable output voltage up to 6 V. The device features an initial accuracy of 1% and a maximum temperature coefficient of 138 PPM/°C. It functions with a minimum cathode current of 80 µA and a maximum sink current of 15 mA. The component is housed in a TO-92-3 package for through-hole mounting and operates across a temperature range from -40°C to +125°C.

Feature Summary

• Adjustable output voltage capability via external resistor divider
• Low voltage operation suitable for battery-powered applications
• High precision with 1% initial accuracy specification

Applications

• Battery-operated equipment requiring precise voltage monitoring
• Data acquisition systems needing stable reference voltages
• Switch-mode power supplies utilizing feedback control loops

Procurement Notes

Verify the specific suffix 'CLP' against the official Texas Instruments datasheet to confirm the package type, temperature grade, and accuracy class match project requirements. Ensure the ordering code corresponds to the exact electrical specifications required for the design. Cross-reference with authorized distributors to validate part authenticity and current production status before finalizing procurement plans.

Selection Notes

Select this component when low-voltage precision regulation is required in a through-hole package. The 1% accuracy and wide operating temperature range make it suitable for industrial applications. Compare the 15 mA maximum sink current against load requirements to ensure adequate drive capability. Consider the TO-92-3 footprint constraints during PCB layout planning.

Part Context

This device belongs to the TLV431 family of low-voltage adjustable shunt regulators. It serves as a high-performance alternative to standard Zener diodes, offering superior stability and lower dynamic impedance. The family is designed for applications where space and power consumption are critical constraints, providing reliable voltage referencing in compact form factors.

Replacement Considerations

Check for direct pin-compatible substitutes such as the TLV431ACLR or TLV431BIDBVTG4 if surface-mount options are preferred. Verify that any replacement maintains the same 1% accuracy and 138 PPM/°C temperature coefficient to ensure circuit performance consistency.
