The RT9193-1HGQW is designed for portable RF and wireless applications with demanding performance and space requirements. The RT9193-1HGQW 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 RT9193-1HGQW also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The RT9193-1HGQW 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.
