MinebeaMitsumi MM1431FN is an adjustable shunt regulator which provides a highly accurate bandgap reference voltage. The output voltage can be adjusted to any value between reference voltage VRef and 35V thanks to two external resistors. There are a lot of ranges of the application as a Zener diode. Besides the replacement is possible because it has steep turn-on characteristics.
MM1431FN features :
- High accuracy reference voltage
