Note Internally limited. When the operating junction temperature rises above 150°C, the internal circuit shuts down

the output voltage.

Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any

parameter. That is, the absolute maximum ratings are rated values at which the product is on the

verge of suffering physical damage, and therefore the product must be used under conditions that

ensure that the absolute maximum ratings are not exceeded.
