These voltage regulators are designed for low power consumption and quiescent current less than 25µA in light load applications.

This is shown in Figure 8. While nRST is low, if the input voltage resumes to the nominal operating voltage, normal power up sequence will be followed.

Depending upon an end application, different values of external components may be used. A larger output capacitor may be required during fast load steps in order to prevent reset from occurring.

This is shown in Figure 15 (a) and (b). Further, heat spreading capabilities of a PCB can be considerably improved by using a thicker ground plane and a thermal land pad with a larger surface area.
