*Input Capacitor C IN Input Capacitor C IN 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 C IN value (refer to conditions of ELECTRIC CHARACTERISTIC) or larger and should connect between GND and V IN as shortest path as possible to avoid the problem. *Output Capacitor C O Output capacitor (C O ) 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 C O 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 C O reduces output noise and ripple output, and also improves output transient response when rapid load change. Therefore, use the recommended C O value (refer to conditions of ELECTRIC CHARACTERISTIC) or larger and should connect between GND and V OUT as shortest path as possible for stable operation The recommended capacitance depends on the output voltage rank. Especially, low voltage regulator requires larger C O 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 C O, 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. - 6 - Ver.214-9-29
*Overshoot of Output Voltage Transient fluctuation of output voltage tends to be large compared to other typical regulators because the NJW4182 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 capacitance is small When output load is light When start up from the condition of narrow voltage difference between an Input and an output. The NJW4182 can reduce overshoot voltage compared to other low current consumption products by a built-in overshoot protection (OSP). However, very large overshoot may occur because of delay of the OSP circuit when the input voltage rises from between 2.V and 2.V. The value of overshoot varies with composite conditions, please refer the above and check the actual condition. 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 rising speed of the input voltage, to avoid rising from between 2.V and 2.V. Ver.214-9-29-7 -
