The TL1431 is a programmable shunt voltage reference with guaranteed temperature stability over the entire operating temperature range. The output voltage may be set to any value between 2.5 V and 36 V with two external resistors. The TL1431 operates with a wide current range from 1 to 100 mA with a typical dynamic impedance of 0.2 Ω. D
■ Adjustable output voltage: VREFto 36 V
■ Sink current capability: 1 to 100 mA
■ Typical output impedance: 0.22Ω
■ 0.4% and 0.25% voltage precision
