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 necessary for power applications, critical in 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.
