TL431 TL432 Automotive adjustable voltage reference Datasheet - production data Applications Power supply Industrial Automotive Z L TO-92 Description SOT23-3 (Plastic package) The TL431 and TL432 are adjustable 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 L C wide current range from 1 to 100 mA with a typical SOT23-5 SOT323-6 dynamic impedance of 0.22 . D SO-8 (Batwing plastic micropackage) Features AEC-Q100 qualified Adjustable output voltage: 2.5 to 36 V Sink current capability: 1 to 100 mA Typical output impedance: 0.22 0.5% voltage precision only on the TL431B version 1% and 2% voltage precision Automotive temp. range -40 C to +125 C February 2021 DocID4467 Rev 15 1/22 This is information on a product in full production. www.st.comContents TL431, TL432 Contents 1 Schematic diagrams . 3 2 Absolute maximum ratings and operating conditions . 4 3 Electrical characteristics . 5 Reference input voltage deviation overtemperature range . 8 4 Package information 12 4.1 SO-8 package information 13 4.2 TO-92 ammopack and tape and reel package information . 14 4.3 TO-92 (bulk) package information 15 4.4 SOT23-3 package information . 16 4.5 SOT23-5 package information . 17 4.6 SOT323-6 package information 18 5 Ordering information . 19 6 Revision history . 21 2/22 DocID4467 Rev 15
