... ADJ/ TRK SOFT START The ADP1715 adjustable version and the ADP1716 have no pins for soft start, so the function is switched to an internal soft- start capacitor. This sets the soft-start ramp-up period to approximately 24 μs. For the worst-case output voltage using the suggested 2.2 μF output capacitor, the resulting input inrush current is approximately 460 mA, which is less than the maximum 500 mA load current ...

... ENABLE FEATURE The ADP1715/ADP1716 use the EN pin to enable and disable the OUT pin under normal operating conditions. As shown in Figure 30, when a rising voltage on EN crosses the active threshold, OUT turns on. When a falling voltage on EN crosses the inactive threshold, OUT turns off ...

... ADP1715/ADP1716. Transient response to changes in load current is also affected by output capacitance. Using a larger value of output capacitance improves the transient response of the ADP1715/ADP1716 to large changes in load current. Figure 32 and Figure 33 show the transient responses for output capacitance values of 2.2 μF and 22 μF. ...

... Heat dissipation from the package is increased by connecting as much copper as possible to the four GND pins of the ADP1715/ ADP1716. From Table 5 it can be seen that a point of diminishing returns eventually is reached, beyond which an increase in the copper size does not yield additional heat dissipation benefits ...
