TL431, TL432
SLVS543S – AUGUST 2004 – REVISED MAY 2024 TL431, TL432 Precision Programmable Reference
1 Features 3 Description • The TL431 and TL432 devices 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
2.5V) and 36V, with two external resistors. These
devices have a typical output impedance of 0.2Ω.
Active output circuitry provides a very sharp turnon characteristic, making these devices excellent
replacements for Zener diodes in many applications,
such as on-board regulation, adjustable power
supplies, and switching power supplies. The TL432
device has exactly the same functionality and
electrical specifications as the TL431 device, but has
different pinouts for the DBV, DBZ, and PK packages. •
