TLV431BIDCKT

Overview

The TLV431BIDCKT is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It features an internal reference voltage of 1.24 V and offers an initial accuracy of ±0.5%. The device supports an adjustable output voltage range from 1.24 V to 6 V, set via two external resistors. It operates within a temperature range of -40°C to 85°C and utilizes a SC-70-6 (SOT-363) surface-mount package.

Feature Summary

• Provides high-precision voltage regulation with ±0.5% initial accuracy at 25°C
• Enables flexible output voltage configuration between the reference level and 6 V using external resistors
• Designed for low-voltage operation suitable for compact power management applications

Applications

• Precision voltage references in portable electronic devices
• Feedback control loops in DC-DC converters
• Battery-powered equipment requiring stable reference voltages

Procurement Notes

Verify the specific suffix IDCKT against the official datasheet to confirm the SC-70-6 package and tape-and-reel packaging format. Ensure compatibility with the required operating temperature range of -40°C to 85°C for the intended application environment.

Selection Notes

Select this component when a compact surface-mount solution is required for low-voltage precision regulation. The ±0.5% tolerance ensures tight voltage stability compared to standard variants. Confirm that the maximum cathode current and voltage limits align with the circuit design requirements.

Part Context

This part belongs to the TLV431 family of low-voltage adjustable precision shunt regulators. It serves as a three-terminal voltage reference alternative to Zener diodes, offering superior thermal stability and lower dynamic impedance. The 'B' designation indicates the ±0.5% accuracy grade within the product line.

Replacement Considerations

Check for direct equivalents such as TLV431AIDCKT or TLV431QIDCKT depending on required accuracy grades or automotive qualification needs.
