(1) This is for capacitors directly at the output of the device. More capacitance is allowed if there is a series resistance associated to the capacitor.
(2) Nominal inductance value.
(3) Larger values of inductance can be used to reduce the ripple current,
but larger values of inductance can have a negative impact on efficiency and the overall
transient response.
(4) Operating lifetime is derated at junction temperatures greater than 165°C.
