NJM431S/NJM432S
ADJUSTABLE PRECISION SHUNT REGULATOR
■ GENERAL DESCRIPTION
The NJM431S/NJM432S are adjustable precision shunt regulators.
The output voltage may be set to any value between VREF
(about 2.5V) and 36V by two resistors.
Compared to the conventional 431, the NJM431S/NJM432S are
improved the voltage accuracy. And they have smaller package
option to support a wide range of applications.
The NJM432S is the pin assignment option.

Note) Oscillation might occur while operating within the range of safety curve.
So that, it is necessary to make ample margins by taking considerations of fluctuation of the device.
