LDO OUTPUT COMPONENTS
Zero999:
If the inductor had a damping resistor in parallel, it would make more sense, since at high frequencies the regulator would see the capacitor, with the series resistance, which would be bypassed, by the low resistance inductor at low frequencies, thus avoiding the associated voltage drop.
A ferrite bead is a good idea because it behaves as an inductor at low frequencies and a resistor at high frequencies, where the regulator is likely to oscillate.
