V CC Power ? up (V AUX = 3.3 V). Figure 7 shows the
output response as V CC approaches the select threshold
during a power ? up when V AUX is present (3.3 V). The
output capacitor is already fully charged. When V CC reaches
the select threshold, the in ? rush current is minimal and the
V CC disturbance is only 130 mV. The built ? in hysteresis of
250 mV ensures the regulator remains enabled throughout
the transient.
during a power ? down transition. V AUX of 3.3 V remains
present. When V CC reaches the deselect threshold (4.1 V),
the regulator turns off. This causes a step change reduction
in V CC current resulting in a small voltage increase at the
V CC input. This disturbance is approximately 100 mV and
the built ? in hysteresis of 250 mV ensures the regulator
remains disabled throughout the transient. The output
voltage experiences a disturbance of approximately 100 mV
during the transition.
V OUT offset = 3.3 V, V CC offset = 4.3 V
V OUT offset = 3.3 V, V CC offset = 4.3 V

V CC Power ? up (V AUX =3.0 V). Figure 8 shows the
output response as V CC approaches the select threshold
during power ? up. The auxiliary voltage, V AUX is set to a low
level of 3.0 V. When V CC reaches the select threshold,
a modest level of in ? rush current is required to further
charge the output capacitor resulting in V CC disturbance of
200 mV. The built ? in hysteresis of 250 mV ensures the
regulator remains enabled throughout the transient.

Load Step Response. Figure 10 shows the output
response of the regulator during a step load change from
5 mA to 500 mA (represented on Ch1). An initial transient
overshoot of 50 mV occurs and the output settles to its final
voltage within a few microseconds. The dc voltage
disturbance on the output is approximately 75 mV, which
demonstrates the regulator output impedance of 0.15 W .
