2. short circuits from the output V
+
can cause excessive heating and eventual destruction. When considering short
circuits to ground the maximum output current is approximately 40mA independent of the magnitude of V
+
values of
supply voltage in excess of +15v,continuous short circuit can exceed the power dissipation ratings and cause
eventual destruction.
