TL431ID Datasheet

Programmable voltage reference


The TL431 and TL432 are programmable shunt voltage references with guaranteed temperature stability over the entire operating temperature range. The device temperature range is extended for the automotive version from -40 °C up to +125 °C. The output voltage can be set to any value between 2.5 and 36 V with two external resistors. The TL431 and TL432 operate with a wide current range from 1 to 100 mA with a typical dynamic impedance of 0.22 Ω. TL431ID Features • Adjustable output voltage: 2.5 to 36 V• Sink current capability: 1 to 100 mA• Typical output impedance: 0.22 Ω• 1% and 2% voltage precision• Automotive temp. range - 40 °C to +125 °C TL431ID Applications • Power supply• Industrial• Automotive
