* The output impedance ROUT can be reduced by parallel connection.

* C3 is a stabilizing capacitor output for stabilized voltage.

* In the parallel connection, one stabilizing capacitor using is better way.

* The IC may have a possibility not to operate properly with unstable supply voltage due to large transient

current when the capacitor is charged or discharged.

The decoupling capacitor (CIN) connect as close as possible to the IC.
