∗1
The power module will be operating when turn on the SW1(10 pin and 7pin shorts)
∗2
Max output current should be reduced according to the surrounding temperature.
∗3
The output ripple voltage may vary depending on the capacitance, environment, and location of peripheral components.
Especially more attention has to be paid to aluminum electrolytic capacitor because ESR changes greatly and output ripple voltages
increase at the time of the low temperature.
