NJM2380/A, NJM2390/A
ADJUSTABLE HIGH PRECISION SHUNT REGULATOR
■
GENERAL DESCRIPTION
The
NJM2380/A, NJM2390/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 SOT23(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.
