INTEGRATED CIRCUITS TL431C, TL431AC, TL431I, TL431AI, LM431AC Adjustable precision shunt regulators Product specification 1997 Feb 25 Philips Semiconductors Philips Semiconductors Product specification Adjustable precision shunt regulators TL431C, TL431AC, TL431I, TL431AI, LM431AC DESCRIPTION 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. Active output circuitry provides a very sharp turn-on...
