For circuit currents, '+' denotes current flowing into the IC, and '−' denotes current flowing out of the IC.
* 1: Except for the operating ambient temperature and storage temperature, all ratings are for T
* 2: The voltage in a step-up voltage circuit exceeds a supply voltage. Refer to "I Electrical Characteristics" for an allowable
