TL431 and TL432 are three -terminal adjustable parallel adjusters
Description/Order Information
TL431 and TL432 are three -ends adjustable parallel adjusters. It has the prescribed thermal stability suitable for automotive, commercial and military temperature range. The output voltage can be set to any value between VREF (about 2.5 V) and 36 V, with two external resistors (see Figure 17). These devices have a typical output impedance of 0.2Ω. The active output circuit provides a very sharp opening feature that allows these devices to be an excellent alternative to the Zina diode in many applications, such as adjustment on the ship, adjustable power and switching power. TL432 has exactly the same function, and electrical specifications such as TL431, but there are different leading lines for DBV, DBZ and PK packaging.
TL431 and TL432 have three levels. The initial tolerance (25 ° C) was 0.5%, 1%, and the standard levels of B, A, and standards were 2%. In addition, the relationship between low output drift and temperature ensures the stability of the entire temperature.
The TL43XXC device is characterized by working at temperatures at 0 ° C to 70 ° C. The TL43XXI device is characterized by running within the temperature range of -40 ° C to 85 ° C. Run 125 degrees Celsius within the temperature range of -40 ° C to 85 ° C.
