Note) *1: Expect for the operating ambient temperature, and storage temperature, all ratings are for Ta = 25°C.

*2: At the application of VIN = 30 V, the overvoltage protection may be operated by the ASO protection circuit, leading to the

output shut down.

*3: The current value does not exceed this criterion because of the on-chip current limiter.

*4: The internal circuit shuts off the output when Tj ≥ 150°C (designed value). The relationship between the IC power

dissipation and ambient temperature shall conform to the derating curve (s Characteristic curve chart PD  Ta).
