TLVH431CLP

Overview

The TLVH431CLP is a low-voltage adjustable precision shunt voltage reference manufactured by Texas Instruments. It operates within a cathode-to-anode 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 shunt current of 80 mA with a minimum operating current of 80 µA. The component functions across an extended temperature range from -40°C to +125°C and is housed in a TO-92-3 through-hole package.

Feature Summary

• Provides adjustable output voltage ranging from 1.24 V to 18 V via external resistor divider
• Ensures high voltage precision with 0.5% initial accuracy specification
• Operates with low quiescent current starting at 80 µA for power efficiency
• Maintains stable performance over an extended industrial temperature range

Applications

• Battery-operated equipment requiring precise voltage monitoring
• Switch-mode power supplies utilizing feedback regulation
• Data acquisition systems needing stable reference voltages
• Portable devices where space-saving through-hole packaging is preferred

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and tolerance grades. Confirm RoHS compliance status and manufacturing origin details directly from the datasheet or purchase order specifications. Ensure the procurement channel sources genuine components to avoid counterfeit risks associated with passive semiconductor devices.

Selection Notes

Select this component when a through-hole package is required for low-voltage applications demanding 0.5% accuracy. Compare against the TLVH431B series if higher precision is needed, or the TLVH431A series if lower cost is prioritized. Ensure the circuit design accommodates the 80 mA maximum sink current capability and the 20 V maximum input voltage limit.

Part Context

This part belongs to the TLVH431 family of low-voltage adjustable shunt references. It serves as a drop-in replacement for standard TL431 devices in low-voltage circuits while offering improved performance characteristics such as lower operating current and tighter initial accuracy tolerances suitable for modern portable electronics.

Replacement Considerations

Consult official substitution guides for equivalent parts like the TLVH431BCLP or TLVH431AILP depending on required accuracy levels. Verify that alternative packages maintain the same electrical characteristics and thermal performance requirements.
