TL431 Description

The TL431 is three-terminal adjustable shunt regulator 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. The TL431 device has a typical output impedance of 0.2 ?. Active output circuitry provides a very sharp turn-on characteristic, making the device excellent replacement for Zener diode in many applications such as onboard regulation, adjustable power supplies and switching power supplies. The TL432 has exactly the same functionality and electrical specifications as the TL431, but has different pinouts for the DBV, DBZ and PK packages. Both the TL431 and TL432 devices are offered in three grades, with initial tolerances (at 25°C) of 0.5 percent, 1 percent, and 2 percent, for the B, A and standard grades, respectively. In addition, low output drift vs. temperature ensures good stability over the entire temperature range.
