(5)

The maximum output current (IOUT) is determined by device power dissipation limitations. See the Power Dissipation section of the

Application Information for more details.

(6)

Short circuit current should be limited in duration to no more than 10 seconds. See the Power Dissipation section of the Application

Information for more details.
