The TL431 and TL432 are three-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive, commercial and military temperature ranges. The output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V with two external resistors. These devices have a typical output impedance of 0.2 O. https://elecena.pl/product/28196298/tl431acdbzr-voltage-reference-adjustable-2-495-36-v-sot-23-3 2025-04-05 https://elecena.pl/product/28196298/tl431acdbzr-voltage-reference-adjustable-2-495-36-v-sot-23-3 2026-01-31
