Note) 1. *1: Except for the operating ambient temperature and storage temperature, all ratings are for Ta
= 25°C.
*2: The power dissipation shown is the value for the independent IC without a heat sink at Ta
= 85°C.
When Tj exceeds 150
°C (designed value), the internal circuit cuts off the output.
2. This IC is not suitable for car electronics equipment.

The specified condition Tj
= 25°C means that the test should be carried out within so short a test time (within 10 ms)
that the characteristic value drift due to the chip junction temperature rise can be ignored.
