Output current rating may be limited by duty cycle, am-

bient temperature, and heat sinking. Under any set of

conditions, do not exceed the specified current rating

or a junction temperature of 150°C.

Range S

Fault conditions that produce excessive junction temperature will activate

the device’s thermal shutdown circuitry. These conditions can be toler-

ated but should be avoided.
