General Description
The RT9193 is designed for portable RF and wireless applications with demanding performance
and space requirements. The RT9193 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 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 consumes less than 0.01μA in shutdown mode and has fast turn-on
time less than 50μs.
