TLV431ACDBVR +BOM

Three-terminal precision reference source

TLV431ACDBVR General Description

Texas Instruments' TLV431ACDBVR is part of the TLV431A series, known for its high-quality voltage reference components. This shunt adjustable type offers a reference voltage range of 1.24V to 6V, allowing for flexibility in design and implementation. With an initial accuracy of 1%, engineers can trust the precision of this product in voltage regulation applications. The compact SOT-23 package style further enhances the usability of the TLV431ACDBVR, making it a popular choice among designers and manufacturers
