*The quantity and quality of bulk input bypass capacitance
needed, particularly for low dropout scenarios (V
< 600mV) is mainly dependent on the output impedance
and dynamic response of the power source feeding the
LTM4611(s). Consider, in the extreme: for a heavy load
step, the full transient on LTM4611’s output is directly

referred to its input, and the LTM4611 can only deliver
to its output whatever the source supply and local input
caps can provide. Sluggish source supplies will call for
more bulk capacitance placed locally to the LTM4611’s
input, to assist the source supply in riding through severe
transient load steps.
