Overview
NJM431 ADJUSTABLE PRECISION SHUNT REGULATOR ■ GENERAL DESCRIPTION The NJM431 is a 3 terminal adjustable shunt regulator.
The output voltage may be set to any value between VREF (about 2.
5V) and 36V by two resistors.
Output circuitry shows a sharp turn-on characteristics.
Applications include shunt regulators, series regulators for small power and isolation regulators with photo couplers.
