Cautions
Short-circuit (power-output short-circuit), ground fault (GND-output short-circuit), load short-circuit protective circuits incorporated. They activated case abnormal connection. These circuits remain active while such abnormal connection continues reset automatically when abnormality removed. certain conditions, protective circuits locked continue active even when abnormality removed. this case, either enter standby mode turn power supply. thermal protection circuit incorporated activated when junction temperature (Tj) rises about 160°C more. output controlled return gradually attenuated state. When product used near maximum rating, even slightest change condition cause exceeding maximum rating, resulting possibly breakdown. Take sufficient margin supply voltage, etc. always product within range never exceeding maximum rating.
