The LME49722 datasheet says the part has short circuit protection but doesn't really say how it works.
Is there more information about this?

One more question, is there a spice model for this part?
Hello Gerry-san,
LME49722 configure emitter followe type output stage for both Source and Sink current and also has resistor for current sense and current detector transistor for monitoring thre voltage across the current sense resistor. If the output current exceeds the short circuit current value, the voltage across the current sensing resistor increases and detector transistor starts activate and this transistor works to supress base current of output transistor then output current will be limited as the result. This will be the behavior about short circuit current limit circuit.
Hope this help for your question.

Hello Gerry-san
We are very sorry, we don't have Spice model for this part.
