The UTC TL431-AB3-R is a three-terminal adjustable shunt voltage reference with a typical temperature coefficient of 50ppm/°C. The output voltage can be set to any value between VREF (approximately 2.5V) and 36V using two external resistors. It features a low dynamic output impedance of 0.2Ω, ensuring stable regulation. The device can sink current from 1mA to 100mA, making it suitable for a variety of applications including voltage monitoring, power supply regulation, and precision reference circuits.
The TL431-AB3-R is offered in a SOT-89 surface-mount package, supplied in tape and reel packaging with a standard quantity of 2000 pieces. It is designed for operation over an ambient temperature range of -40°C to +85°C, with an absolute maximum junction temperature of +150°C. The part is lead-free as indicated by the 'K' in the part number. For reliable performance, the recommended operating conditions include a cathode voltage up to 36V and cathode current between 1mA and 100mA.
