NJM78M00
3-TERMINAL POSITIVE VOLTAGE REGULATOR
GENERAL DESCRIPTION
The NJM78M00 series of 3-Terminal Positive Voltage Regulators
is constructed using the New JRC Planar epitaxial process. These
regulators employ internal current-limiting, thermal-shutdown and
safe-area compensation making them essentially indestructible. If
adequate heat sinking is provided, they can deliver in excess of
500mA output current. They are intended as fixed voltage regulation
in a wide range of applications including local or on-card regulation
for elimination of noise and distribution problems associated with
single point regulation. In addition to use as fixed voltage regulators,
these devices can be used with external components to obtain
adjustable output voltages and currents.

Input Capacitor CIN
Input Capacitor CIN is required to prevent oscillation and reduce power supply ripple for applications when high
power supply impedance or a long power supply line.
Therefore, use the recommended CIN value (refer to conditions of ELECTRIC CHARACTERISTIC) or larger and
should connect between GND and VIN as shortest path as possible to avoid the problem.
Output Capacitor CO
Output capacitor (CO) will be required for a phase compensation of the internal error amplifier.
The capacitance and the equivalent series resistance (ESR) influence to stable operation of the regulator.
Use of a smaller CO may cause excess output noise or oscillation of the regulator due to lack of the phase
compensation.
On the other hand, Use of a larger CO reduces output noise and ripple output, and also improves output
transient response when rapid load change.
Therefore, use the recommended CO value (refer to conditions of ELECTRIC CHARACTERISTIC) or larger
and should connect between GND and VOUT as shortest path as possible for stable operation
In addition, you should consider varied characteristics of capacitor (a frequency characteristic, a temperature
characteristic, a DC bias characteristic and so on) and unevenness peculiar to a capacitor supplier enough.
When selecting CO, recommend that have withstand voltage margin against output voltage and superior
temperature characteristic though
