ADJUSTABLE HIGH PRECISION SHUNT REGULATOR
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
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.
■ FEATURES
● Operating Voltage (VREF to 18V)
● High Precision Voltage Reference (2.465V±2%)
(2.465V±1% : A Version)
● Mounted in Ultra Mini Package (MTP5)
● Minimum External Parts
● Bipolar Technology
● Package Outline DIP8, DMP8, EMP8,
SOT-89 (3pin), TO-92, MTP5

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.
