Output current rating may be limited by duty cycle, ambient temperature, and heat sinking. Under any
set of conditions, do not exceed the specified current rating or a junction temperature of 150 ° C.
Note 1: When ambient temperature is 25 ° C or over, derate using − 32.0mW/° C.
Note 2: Fault conditions where junction temperature (T j ) exceeds 150°C will activate the device ’s thermal
shutdown circuitry. These conditions can be tolerated but should be avoided
