TLV431BCDBVRG4

Overview

The TLV431BCDBVRG4 is a low-voltage adjustable precision shunt regulator from Texas Instruments, housed in an SOT-23-5 surface-mount package. It provides an adjustable output voltage range of 1.24 V to 6 V with an initial accuracy of ±0.5%. The device supports a maximum cathode current of 15 mA and operates within a temperature range of -40°C to +85°C. Key electrical specifications include a maximum input voltage of 7 V and a typical temperature coefficient of 138 ppm/°C.

Feature Summary

• Adjustable output voltage capability spanning from 1.24 V up to 6 V for flexible circuit design
• High initial accuracy of ±0.5% ensures precise voltage regulation performance
• Low-voltage operation suitable for battery-powered and portable electronic applications

Applications

• Portable equipment requiring stable reference voltages
• Battery-operated devices needing efficient power management
• General-purpose voltage regulation in compact circuits

Procurement Notes

Verify the specific suffix 'RG4' indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the SOT-23-5 package variant matches your PCB footprint requirements. Ensure the operating temperature range of -40°C to +85°C aligns with your system's environmental conditions before finalizing procurement.

Selection Notes

Select this component when a high-accuracy (±0.5%) adjustable shunt regulator is required in a small SOT-23-5 package. It is suitable for applications where space is limited but precision is critical. Consider the 15 mA current limit and 7 V maximum input voltage when designing the surrounding circuitry to ensure safe operation within specified limits.

Part Context

This part belongs to the TLV431B series of low-voltage adjustable precision shunt regulators. It serves as a drop-in replacement for traditional Zener diodes in many regulation scenarios, offering superior stability and adjustability. The family is designed for cost-sensitive, high-volume consumer electronics where reliable voltage referencing is essential.

Replacement Considerations

Direct equivalents may include other TLV431 variants with different accuracy grades or packages, such as TLV431AIDBVR1G4 (1% accuracy) or TLV431IDBVRG4 (1.5% accuracy). Verify pinout compatibility and thermal characteristics when substituting with non-Texas Instruments parts.
