TLVH431ILPE3

Overview

The TLVH431ILPE3 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It features an adjustable output voltage range from 1.24 V to 18 V with an initial accuracy of 0.5%. The device operates with a maximum input voltage of 20 V and supports a maximum shunt current of 80 mA. It has a temperature coefficient of 138 ppm/°C and functions within a temperature range of -40°C to +125°C. The component is housed in a SOT-23-5 surface-mount package.

Feature Summary

• Provides adjustable reference voltage functionality for precision circuit applications
• Ensures stable performance across a wide industrial temperature range
• Designed for space-constrained designs using compact surface-mount packaging

Applications

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

Procurement Notes

Verify the specific suffix ILPE3 against the manufacturer's latest documentation to confirm package type, accuracy grade, and tape/reel specifications. Ensure compatibility with the target PCB footprint for the SOT-23-5 package. Confirm that the 0.5% initial accuracy meets the design requirements for the intended application environment.

Selection Notes

Select this component when a low-voltage adjustable shunt regulator with high precision (0.5%) is required. It is suitable for applications where space is limited due to its small SOT-23-5 form factor. Consider the 138 ppm/°C temperature coefficient for thermal stability needs. Compare against standard TL431 variants if higher current or different voltage ranges are needed.

Part Context

This part belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators from Texas Instruments. These devices are designed as alternatives to traditional bandgap references, offering lower operating currents and better performance in low-voltage environments. The family includes various packages and accuracy grades to suit diverse electronic design constraints.

Replacement Considerations

Check for direct substitutes such as TLVH431AIDBVR or other TI shunt regulators with matching SOT-23-5 packaging and 0.5% accuracy. Verify pinout compatibility and electrical parameters before substitution.
