7. Functional diagram
The TLVH431 family compr ise s a ran ge of 3- te rm in al ad jus table shun t re gu lat or s, 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 circui try prov id es a very sh ar p tur n -o n ch ar ac ter i st ic ,
making these devices excellent replacements for Zener diodes in many applications like
on-board regulation, adjustable power supplies and switching power supplies.
