−30 to +85
−55 to +150
Note) 1. *1: Except for the operating ambient temperature and storage temperature, all ratings are for Ta = 25°C.
*2: When VCC of 35 V is applied, the overvoltage protection of ASO protection circuit may shut off the output.
*3: Since this IC has incorporated a current limiter, the current value does not exceed the rating.
*4: When Tj exceeds 150°C (designed value), the internal circuit cuts off the output. Note that the relationship between IC
power dissipation and the ambient temperature must follow the derating curve.
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.
