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.
