RT9198-50GB Products

The RT9198/A is designed for portable RF and wireless applications with demanding performance and space requirements. The RT9198/A 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 RT9198/A also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The RT9198/A 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 SOT-23-3, SOT-23-5, TSOT-23-3, TSOT-23-5, SC-70-5, SC-82, MSOP-8 and WDFN-6L 2x2 packages, the RT9198/A also offers a range from 1.5V to 5.0V with 0.1V per step.
