Setup
Figure 1 shows the input (Ch. 1, 5 V/div), output (Ch. 2, 5 V/div), overcurrent (Ch. 3, 5 V/div), and the
enable input (Ch. 4, 5 V/div). Because enable is in a logic-high state, 0 volts is observed at the output.

Figure 2 shows the enable input toggled from a logic-high (Ch. 4) to a logic-low state. When this occurs,
the output shoots up to 5 V (Ch. 2).
