Description

The TL431BIDB 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 impeda ce of 0.2 Ω. Active output circuitry provides a very sharp tu n-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. TL431BIDB Features • Operation From −40°C to 125°C• Reference Voltage Tolerance at 25°C 0.5% . . . B Grade 1%. . . A Grade 2% . . .
