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.

RT9065GE属于集成电路（IC） > 线性 + 开关稳压器。立绮科技制造生产的RT9065GE稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。
