TS431 Adjustable shunt voltage reference IC (automotive for SOT23-5) Datasheet - production data Description Z The TS431 is a low-voltage, three-terminal, TO92 adjustable shunt voltage reference. The output (plastic package) voltage can be set to any value between V ref (1.24 V) and 6 V using two external resistors. The TS431 is able to operate at a lower voltage (1.24 V) and lower cathode current than the widely- L used TL431 and TL1431 shunt voltage reference. SOT23-5 When driving an optocoupler, the TS431 is (plastic micropackage) particularly suitable for regulating 3.3 V switching power supplies. Features AEC-Q100 qualified (SOT23-5) Low voltage operation: 1.24 to 6 V 2%, 1% and 0.5% voltage precision Wide operating range cathode current: 60 A to 30 mA Low output impedance: 0.2 Typically stable for any capacitive loads ESD protection: Human body model: 2 kV Machine model: 200 V 100 ppm/C temperature coefficient Automotive grade version available June 2018 DocID5558 Rev 12 1/16 This is information on a product in full production. www.st.comContents TS431 Contents 1 Pinout . 3 2 Absolute maximum ratings and operating conditions . 4 3 Electrical characteristics . 5 Definition of output voltage change over temperature range . 5 4 Application information 9 5 Package information 10 5.1 SOT23-5 package information 11 5.2 TO92 (tape ammopack and tape and reel) package information . 12 5.3 TO92 (bulk) package information . 13 6 Ordering information . 14 7 Revision history . 15 2/16 DocID5558 Rev 12
