Maximum output current varies depending on ambient temperature ; please refer to derating curve.
∗2
The output ripple voltage may vary depending on the capacitance, environment, and location of peripheral components. Particular
attention must be paid to aluminum electrolytic capacitor, because ESR changes greatly at the time of the low temperature and output ripple
voltages increase.
