The Texas Instruments TL431QDCKR is a three-terminal adjustable precision 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.
Key electrical characteristics include a reference voltage tolerance of 0.5% at 25°C (for B grade), a typical output impedance of 0.2Ω, and a sink current capability ranging from 1mA to 100mA. The device operates reliably from -40°C to 125°C.
Packaged in a 6-pin SOT-SC70 (DCK) surface-mount package, the TL431QDCKR is suitable for various on-board regulation and adjustable power supply applications. Its active output circuitry provides a sharp turn-on characteristic, making it an effective replacement for Zener diodes in many designs.
