General Description
The RT9065 is designed for portable RF and wireless
applications with demanding performance and space
requirements. The RT9065 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 RT9065 also works with low-ESR ceramic
capacitors, reducing the amount of board space necessary
for power applications, critical in hand held wireless
devices. The RT9065 consumes less than 0.01μA in
shutdown mode. The other features include low dropout
voltage, high output accuracy, current limiting protection,
and high ripple rejection ratio. The RT9065 is available in
the SOT-23-6 package.
