NJW4181
High Voltage Very low current consumption Io=100mA Regulator
GENERALDESCRIPTION
PACKAGE OUTLINE
The NJW4181 is a high input voltage and low current consumption
100mA series regulator lowcurrentconsumption Iq=9µA and small package.
It has two package lineup. SOT-89 is able to direct replace to
3-terminal 78L series. ESON6, tiny DFN package, corresponds to
a demand on miniaturization of sensor application and so on.
Due to the low current consumption of 9µA, the NJW4181 is suitable
for light load and continuously running applications such as power
management microprocessor, RTC, protection circuit, security system
and so on.

*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 the VIN pin 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 the VOUT pin 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.
*Reverse Current Protection
NJW4181 is built-in a Reverse Current Protection. This circuit restrains reverse current from the VO pin to the VIN pin
when the input voltage is less than the output voltage.
In case of the voltage rank 5.0V or below, reverse voltage differential between output and input should keep VIN+7V
or less, to prevent IC breaking due to huge reverse current.
And also, the absolute maximum ratings of the Vo pin (17V) should not be exceeded.
