NJM2380/A
ADJUSTABLE HIGH PRECISION SHUNT REGULATOR
■
GENERAL DESCRIPTION
The
NJM2380/A
is an adjustable high precision
shunt regulator.
It is adapted for downsizing power supply module,
battery charger and others, because an ultra mini
package (MTP5) is included in the package line-up.

Note) Oscillation might occure while operating within
the range of sefety curve.
So that, it is necessary to make ample margins
by taking considerations of fluctuation of the
device.
