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.
