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.
