DESCRIPTION
The FT533xx is designed for portable RF and
wireless applications with demanding performance
and space requirements. The FT533xx performance is
optimized for battery powered systems to deliver
ultra low noise and low quiescent current. Regulator
ground current increases only slightly in dropout,
further prolonging the battery life.
The FT533xx also works with low-ESR ceramic
capacitors, reducing the amount of board space

hand-held wireless devices. The FT533xx consumes
less than 0.1μA in shutdown mode and has fast
turn-on time less than 25μS. The other features
include low dropout voltage, high output accuracy,
current limiting protection, and high ripple rejection
ratio. The FT533xx is available in the 5-lead of
SOT-23-5(L), SC-70 and the 3-lead of SOT-23-3(L),
SOT-89-3(L), SOT-23 packages.
