ADJUSTABLE PRECISION SHUNT REGULATOR

■ GENERAL DESCRIPTION

■ PACKAGE OUTLINE

The NJM431S/NJM432S are adjustable precision shunt regulators.

(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.
