The TL431 and TL431A 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 V
ref (approximately 2.5 V) and 36 V, with two
external resistors (see Figure 17). These devices have a typical output impedance of 0.2 .
Active output circuitry provides a very sharp turn-on characteristic, making these devices
excellent replacements for Zener diodes in many applications, such as onboard regulation,
adjustable power supplies, and switching power supplies.
The TL431C and TL431AC are characterized for operation from 0°C to 70°C, and the TL431I
and TL431AI are characterized for operation from -40°C to 85°C.
