The SGM431x is a three-terminal adjustable shunt regulator, with specified thermal stability over applicable commercial, industrial and extended industrial temperature ranges. The output voltage can be set to any value between VREF (approximately 2.5V) and 36V, with two external resistors. The SGM431x has a typical output impedance of 0.1Ω. Active output circuitry provides a very sharp turn-on characteristic, making it an excellent replacement for Zener diodes in many applications, such as onboard regulation, adjustable power supplies and switching power supplies.
In addition, low output drift versus temperature ensures good stability over the entire temperature range.
