The figure above shows the recommended configuration for using a Low-Dropout regulator. Insert a capacitor at
V_OUT and V_IN pins for stable input/output operation. (Ceramic capacitors can be used)
If the control function is not used, Toshiba recommend that the control pin is connected to the V_IN pin.
