The Texas Instruments TL431AIDBZR is a three-terminal adjustable shunt regulator designed for applications requiring precise voltage regulation. It allows the output voltage to be set anywhere between Vref (approximately 2.5V) and 36V using two external resistors. This device exhibits specified thermal stability over automotive, commercial, and military temperature ranges.
Key electrical characteristics include a typical output impedance of 0.2Ω and a sink-current capability ranging from 1mA to 100mA. The voltage tolerance at 25°C is 0.5% for the B grade. The operating temperature range is from -40°C to 125°C, with typical temperature drift values specified for different temperature grades.
Packaged in a SOT-23 (DBZ) package, the TL431AIDBZR is suitable for surface-mount designs. Its active output circuitry provides a sharp turn-on characteristic, making it a versatile replacement for Zener diodes in various applications such as on-board regulation and adjustable power supplies.
