*In the case of using a resistance "R" between VIN and control.
If this resistor is inserted, it can reduce the control current when the control voltage is high.
The applied voltage to control pin should set to consider voltage drop through the resistor “R” and the minimum
control voltage for ON-state.
The VCONT (ON) and ICONT have temperature dependence as shown in the "Control Current vs. Temperature" and "
Control Voltage vs. Temperature" characteristics. Therefore, the resistance "R" should be selected to consider the
temperature characteristics.
*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
The recommended capacitance depends on the output voltage rank. Especially, low voltage regulator requires larger
CO value.
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.

*The notes of the evaluation when the VOpin is shorted to GND
When evaluated short circuit test, the IC may break down because of regenerated energy by the parasitic inductance
included in wiring pattern.
It phenomenon appears conspicuously when output voltage is high(Vo=8.0V or more)or connected to inductive load.
In case of short circuit in actual application, not likely to destruction of IC because of some of Resistance exist
between load.
If happened above phenomenon by the short circuit test with the actual application, recommend connecting schottky
barrier diode(SBD) between the VO pin and GND or using output capacitors that have ESR more than 2Ω like a
tantalum or aluminum electrolytic capacitor.(see below figure)

*Overshoot of Output Voltage
Transient fluctuation of output voltage tends to be large compared to other typical regulators because NJW4184 is
designed with the concept of low current consumption characteristics.
In general, overshoot or undershoot of output voltage is more likely to occur when the following cases.
When input voltage or output current fluctuate sharply
When output capacitors is small
When output load is small
When start up from the narrow state between Input and output.
NJW4184 has built in overshoot protection (OSP) circuit and the aim of reducing the overshoot compared to the low
current consumption typical products.
However, there are cases that very large value of overshoot may occur because of delay of the OSP circuit when the
input voltage rises from 2.0V to 2.5V.
Overshoot value since the amount will vary with compound conditions, please check it with the actual environment
reference to the above.
In addition, the following measures will be mentioned as a method to reduce the overshoot value.
a. By increasing the input and output capacitors to absorb overshoot value.
b.Adjust the timing of the CONTROLpin voltage and rising speed of input voltage, to avoid the rise form 2.0V to 2.5V.
When using other power supply to CONTROL pin it is effective
to making the CONTROL pin to Low level at the range of VIN
voltage from 2.0V to 2.5V.

However when it is difficult to control of CONTROLpin by another
power supply, it is possible to same control by dividing the input
voltage with resistance as shown in the left figure.
CONTROL
GND
(Application example)
In the case of R1=100kΩ/R2=30kΩ, since the CONTROL pin
voltage is below 0.6V when VIN = 2.5V, the VOUT is the OFF state.
Resistor divider ratio should be set consider to “Control Voltage
for ON-State” and ambient temperature.
