Operation From -40°C to 125°C Reference Voltage Tolerance at 25°C ­ 0.5% . B Grade ­ 1% . A Grade ­ 2% . Standard Grade Typical Temperature Drift (TL431B) ­ 6 mV (C Temp) ­ 14 mV (I Temp, Q Temp) Low Output Noise 0.2- Typical Output Impedance Sink-Current Capability . 1 mA to 100 mA Adjustable Output Voltage . Vref to 36 V DESCRIPTION
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 (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 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%, 1%, and 2%, for the B, A, and standard grade, respectively. In addition, low output drift vs temperature ensures good stability over the entire temperature range. The TL43xxC devices are characterized for operation from 0°C to 70°C, the TL43xxI devices are characterized for operation from ­40°C to 85°C, and the TL43xxQ devices are characterized for operation from ­40°C to 125°C. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disc...
