RT9065GE集成电路（IC）的线性+开关稳压器规格书PDF中文资料

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.
