During a line transient, the response of this LDO to a very large or fast input voltage change can cause a brief shutdown lasting up to a few hundred microseconds from the voltage transition. This shutdown can be avoided by reducing the voltage step size, increasing the transition time, or a combination of both. Figure 39 provides a boundary to follow to avoid this behavior. If necessary, reduce slew rate and the voltage step size to stay below the curve.
