LA42052 no.a0314-5/7 usage notes 1. lightening (power supply - output short-circuit) and ground fault (gnd - output short-circuit) protective circuits are not incorporated. due care must be taken during handling of the product. 2. the thermal protective circuit is incorporated and activ ated when the junction temperature (tj) rises above about 160 c. this circuit controls the output gradually to the attenuated condition. 3. always ensure the sufficient margin for the supply volta ge, etc. to operate the produc t within the area where the maximum rating will never be exceeded. namely, the maximu m rating may be exceeded due to the slight change in conditions, resulting in damage, if the product is used around the maximum rating.
