New Japan Radio NJM432S
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.

The maximum value of Dynamic Impedance, Reference Voltage Changeand Reference Input Current Change
are determined based on sampling evaluation from the initial production lots, and thus not tested in the production test.
Therefore, these values are for the reference design purpose only.
