Note1: For normal usage, the maximum current value should be determined by heat calculation.
The maximum output current may be further limited depending on ambient temperature and board conditions
(heat conditions).
Note2: Device alone (Ta =25°C)
Ta: Ambient temperature
Topr: Ambient temperature while the IC is active
Tj: Junction temperature while the IC is active. Tj (max) is limited by the thermal shutdown (TSD) threshold.
Please set the usage conditions so that the peak Tj is kept under 120°C for indication.
Caution) Absolute maximum ratings
The absolute maximum ratings of a semiconductor device are a set of ratings that must not be exceeded, even for a
moment. Do not exceed any of these ratings. Exceeding the rating (s) may cause device breakdown, damage or
deterioration, and may result in injury by explosion or combustion. The value of even one parameter of the absolute
maximum ratings should not be exceeded under any circumstances. All voltage ratings, including supply voltages, must
always be followed. Other notes and considerations described in the datasheet should also be referred to.

Note1: The actual maximum current may be limited due to operating circumstances (operating conditions of step resolution,
continuous operation time, etc. and thermal conditions of ambient temperature, PCB layout, etc.)
