Functional diagram The TLVH431 family comprises a range of 3-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive and commercial temperature ranges. The output voltage can be set to any value between Vref (approximately 1.24 V) and 18 V with two external resistors (see Figure 10). These devices have a typical output impedance of 0.1 . Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications like on-board regulation, adjustable power supplies and switching power supplies.
