1.Description The UMW TL431 is an adjustable three-terminal shunt regulator with excellent thermal stability over operating temperature range. The output voltage can be set to any value between Vref (approximately 2.5V) and 36V through external resistors. It provides a very sensitive turn-on characteristic, which makes it possible to replace Zener diodes in many applications. 3.Pinning Information UMW TL431xIDBZR Precision Adjustable Shunt Regulator 2.Features Adjustable output voltage: up to 36V Low dynamic output impedance: 0.3Ω Sink current capability: 1.0~100mA Equivalent full-scale temperature coefficient: typ. 50ppm/°C Temperature compensation in the rated operating temperature range Low output noise Fast start-up response 3 Anode Cathode 1 2 Ref SOT-23 UTD Semiconductor Co.
