TL431 TL432 Programmable voltage reference Datasheet production data Features Adjustable output voltage: 2.5 to 36 V Sink current capability: 1 to 100 mA Typical output impedance: 0.22 1% and 2% voltage precision Z L TO-92 Automotive temp. range - 40 C to +125 C SOT23-3 (Plastic package) Applications Power supply Industrial Automotive L C Description SOT23-5 SOT323-6 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 D resistors. The TL431 and TL432 operate with a SO-8 wide current range from 1 to 100 mA with a typical (Batwing plastic micropackage) dynamic impedance of 0.22 .
