TL431B
TL431B is Automotive adjustable voltage reference manufactured by STMicroelectronics.
- Part of the TL431 comparator family.
- Part of the TL431 comparator family.
Description
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 wide current range from 1 to 100 m A with a typical dynamic impedance of 0.22 Ω.
