* 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 VIN as shortest path as possible to avoid the problem.

* Output Capacitor CO (MLCC) 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 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 though this product is designed stability works with wide range ESR of capacitor including low ESR products.

* Noise bypass Capacitor Cp

Noise bypass capacitor Cp reduces noise generated by band-gap reference circuit. Noise level and ripple rejection will be improved when larger Cp is used. Use of smaller Cp value may cause oscillation. Use the Cp recommended value larger (refer to conditions of ELECTRIC CHARACTERISTIC) to avoid the

problem.

* Reverse Current Protection NJM11100 is built in Reverse Current Protection circuit.

So external Schottky barrier diode(SBD) is not required that this circuit prevents the large reverse current due to the output voltage being higher than the input voltage.
