NJM78L00S
3-TERMINAL POSITIVE VOLTAGE REGULATOR
■ GENERAL DESCRIPTION
The NJM78L00S is a 100mA output 3-Terminal Positive Voltage
regulator.
It has improvements in contrast with a conventional NJM78L00:
an output voltage accuracy, an operating temperature range and
MLCC correspondence. Moreover, the NJM78L00s has 3.3V output
voltage version.

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 VINas 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 this product is designed stability works with wide range ESR of capacitor including low ESR
products.
