∗1:
Maximum output current must be reduced by ambient temperature.
∗2:
An output ripple voltage sometimes changes in capacitor to use, the measurement environment.
Especially right attention has to be paid to aluminum electrolytic capacitor,because ESR changes greatly
at the time of the low temperature and output voltages increase.
