TLVH431AIPK

Overview

The TLVH431AIPK is a precision programmable shunt regulator from Texas Instruments, designed for low-voltage applications. It features a typical reference voltage of 0.925 V with an initial accuracy of ±0.6% at room temperature. The device operates within a wide supply voltage range and supports cathode currents up to 100 mA. It utilizes a SOT-23 surface-mount package, ensuring compact integration in space-constrained designs while maintaining stable regulation characteristics under varying load conditions.

Feature Summary

• Provides precise voltage referencing with high initial accuracy for sensitive analog circuits
• Operates effectively in low-voltage environments suitable for battery-powered systems
• Supports high cathode current capability for robust load driving performance

Applications

• Portable consumer electronics requiring compact voltage regulation
• Battery-operated devices needing efficient power management
• Low-voltage adapter circuits in telecommunications equipment

Procurement Notes

Verify the specific suffix 'AIPK' matches your design requirements, as it denotes the SOT-23 package and tape-and-reel quantity. Confirm that the ±0.6% accuracy class aligns with your system's tolerance needs. Ensure thermal management considerations are addressed for the small outline transistor package during PCB layout. Cross-reference official datasheets for absolute maximum ratings before finalizing procurement orders.

Selection Notes

Select this component when space constraints necessitate a SOT-23 footprint alongside precise voltage control. Consider its low standby current consumption if power efficiency is critical. Evaluate the operating voltage range against your system's minimum supply levels. Compare initial accuracy specifications against other programmable shunt regulators to ensure compliance with strict tolerance requirements.

Part Context

This part belongs to Texas Instruments' TLVH431 family of programmable shunt regulators. These components serve as alternatives to Zener diodes, offering superior stability and lower dynamic impedance. The series is widely used in feedback loops for switching power supplies and linear regulators. The AIPK variant specifically indicates the standard commercial grade with defined electrical characteristics.

Replacement Considerations

Check for direct pin-compatible substitutes like the TLV431AIDBZR or similar TI shunt regulators. Verify that alternative parts match the 0.925 V reference voltage and SOT-23 package dimensions. Ensure equivalent current handling capabilities and accuracy grades are maintained in any replacement selection.
