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 the step-up voltage circuit exceeds the supply voltage.
* 3: The power dissipation shown is the value of independent IC without a heat sink at T
* 4: o = 17, 18, 21, 22, 23, 24, 25, 26, 27, 28, 31, 32
* 6: n = 2, 3, 4, 5, 6, 7, 8, 9, 11, 30
For the allowable value of the step-up voltage, refer to "■ Electrical Characteristics".
of the "■ Application Notes" for details.
