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 V_REF (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.
