The Texas Instruments TL431IDBVR is a three-terminal adjustable shunt regulator designed for stable operation over a wide temperature range. Its output voltage can be precisely set between Vref (approximately 2.5V) and 36V using two external resistors. This device features a typical output impedance of 0.2Ω and a sink-current capability from 1mA to 100mA.
With a reference voltage tolerance of 0.5% at 25°C (B grade), the TL431IDBVR is suitable for applications requiring accurate voltage regulation. It operates reliably from -40°C to 85°C, making it versatile for various environmental conditions. The SOT-23 package is ideal for space-constrained designs.
This shunt regulator serves as an excellent replacement for Zener diodes in applications such as on-board regulation and adjustable power supplies. Its active output circuitry ensures a sharp turn-on characteristic, enhancing its performance in demanding circuits.
