Richtek RT9528GQW

锂离子1.2A-40°C ~ 85°C（TA）

Overview

The RT9193-28GQW is designed for portable RF and wireless applications with demanding performance and space requirements. The RT9193-28GQW 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 RT9193-28GQW also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The RT9193-28GQW consumes less than 0.01μA in shutdown mode and has fast turn-on time less than 50μs. The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. Available in the SC-70-5, SOT-23-5, TSOT-23-5, WDFN-6L 2x2 and MSOP-8 packages.
