Precision Adjustable Shunt Regulator
MM1431 Series
Outline
This IC is 3-termial adjustable shunt regulator, which provides a highly accurate 0.8% bandgap reference
voltage. The output voltage can be adjusted to any value between reference voltage VREF and 35V with
two external resistors. Moreover, 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.
(Unless otherwise specified, Topr=+25°C)

Notes concerning stability operation region
The MM1431AT/AN requires external capasitors for regulator stability. These capacitors must be correctly
selected for good performance.
