TL431AI Overview
The TL431 and TL431A are 3-terminal adjustable shunt regulators with specified thermal stability over applicable automotive and mercial temperature ranges. The output voltage may be set to any value between VREF (approximately 2.5V) and 36V with two external resistors (see Figure 4). These devices have a typical output impedance of 0.2Ω.
