TLV431BIPK

Overview

The TLV431BIPK is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It features an initial accuracy of ±0.5% at 25°C and operates within a temperature range of -40°C to 85°C. The device provides an adjustable output voltage ranging from the internal reference of approximately 1.24V up to 6V. It is housed in a compact SOT-89-3 surface-mount package, designed for applications requiring high precision and stability in power management circuits.

Feature Summary

• Provides high-precision voltage regulation with ±0.5% initial accuracy at room temperature
• Supports low-voltage operation with an adjustable output range starting from approximately 1.24V
• Designed for compact designs using a small SOT-89-3 surface-mount package

Applications

• Low-voltage adjustable power supplies
• Precision voltage references in battery-powered devices
• Feedback control loops in switching regulators

Procurement Notes

Verify the specific suffix IPK corresponds to the SOT-89-3 package and commercial temperature grade (-40°C to 85°C) as defined in the official Texas Instruments datasheet. Confirm RoHS compliance status and ensure the ordering part number matches the exact pinout and marking requirements for your PCB layout before finalizing procurement.

Selection Notes

Select this component when a precise, low-voltage shunt regulator is required with tight initial accuracy tolerances. The SOT-89-3 package offers a balance between thermal performance and board space efficiency compared to smaller packages. Ensure the application voltage does not exceed the maximum rated limit of 6V for this specific low-voltage variant.

Part Context

This device belongs to the TLV431 family of low-voltage adjustable precision shunt regulators from Texas Instruments. Unlike the standard TL431 series which supports higher voltages up to 36V, the TLV431 series is optimized for lower voltage applications, offering improved performance characteristics such as lower noise and better accuracy in low-voltage regimes.

Replacement Considerations

Direct replacements include other TLV431 variants with compatible packages and accuracy grades, such as TLV431AIPK or TLV431CIPK, provided the accuracy tolerance meets design requirements. Cross-brand equivalents like the RC0431 may be considered if pin compatibility and electrical specifications are verified against the official datasheet.
