SHORT CIRCUIT OPERATION
Vout and Ground without damage. When a short occurs, the
pulsed output current increases to the maximum peak value
until the output voltage drops below 1 V. At this point, the
pulsed current is limited to 40 mA average (typical), until
the short is removed. The waveforms given in Figure 16
illustrate the functional operation. Similarly, the input
current is limited 300 mA peak (typical) as depicted in
Figure 17.
The circuit is designed to support a short circuit across
