The RT9193T is designed for portable RF and wireless applications with demanding performance and space requirements. The RT9193T performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current. A noise bypass pin is available for further reduction of output noise. Regulator ground current increases only slightly in dropout, further prolonging the battery life. The RT9193T also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The RT9193T consumes less than 0.01uA in shutdown mode and has fast turn-on time less than 50ms. RT9193T is short circuit thermal folded back protected. RT9193T lowers its OTP trip point from 165°C to 110°C when output short circuit occurs (V_OUT < 0.4V) providing maximum safety to end users. The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. Available in the 5-lead of SC-70, SOT-23 and WDFN-6L 2x2 packages.
