It provides a 2.495 V reference with ±2.2% tolerance and can sink up to 100 mA cathode current, making it suitable for series-pass regulators, error amplifiers, and precision limiters in industrial control and power-supply feedback loops operating from -40 to 85 °C.
The ±2.2% tolerance on the 2.495 V reference sets the output-voltage accuracy for the entire regulation loop.
The TL431IDBVR is supplied in an SOT-23-5 package (SC-74A, SOT-753 case code).
The TL431IDBVR has a 100 mA maximum cathode current and requires a minimum of 1 mA to maintain regulation.
The key difference is the tolerance grade: the TL431AIDBVR offers a tighter ±1% tolerance, while the TL431IDBVR is specified at ±2.2%. Both share the same SOT-23-5 package and 100 mA cathode current rating.
