Notes) *1 : The values under the condition not exceeding the above absolute maximum ratings and the power dissipation.
*2 : The power dissipation shown is the value at T_a = 70°C for the independent (unmounted) IC package without a heat sink.
When using this IC, refer to the P_D-T_a diagram of the package standard and design the heat radiation with sufficient margin so that the
allowable value might not be exceeded based on the conditions of power supply voltage, load, and ambient temperature.
*3 : Except for the power dissipation, operating ambient temperature, and storage temperature, all ratings are for T_a = 25°C.
*4 : Do not apply external currents or voltages to any pin not specifically mentioned.
For the circuit currents, "+" denotes current flowing into the IC, and "−" denotes current flowing out of the IC.
