The RT9017 is designed for portable RF and wirelessapplications with demanding performance and spacerequirements. The RT9017 performance is optimized forbattery-powered systems to deliver ultra low noise andlow quiescent current. Regulator ground current increasesonly slightly in dropout, further prolonging the battery life.The RT9017 also works with low-ESR ceramic capacitors,reducing the amount of board space necessary for powerapplications, critical in hand-held wireless devices. TheRT9017 consumes less than 0.01μA in shutdown modeand has fast turn-on time less than 50μs. RT9017 is shortcircuit thermal folded back protected. RT9017 lowers itsOTP trip point from 165°C to 110°C when output shortcircuit occurs (VOUT < 0.4V) providing maximum safety toend users. The other features include ultra low dropoutvoltage, high output accuracy, current limiting protection,and high ripple rejection ratio. Available in the SOT-23-3,SOT-23-5 and WDFN-6L 2x2 packages, the RT9017 alsooffers a range of 1.5V to 3.5V with 0.1V per step.
