RT9198/A 是針對無線射頻應用的性能需求和空間考慮而設計的產品,具有極低的雜訊和靜態電流消耗。即使是工作在直通狀態下,其電流消耗也只有輕微的增加,可有效延長電池使用時間。它可與低 ESR 陶瓷電容配合穩定工作,對空間需求極低,這對掌上型無線應用至關重要。RT9198/A 在關機模式下僅消耗低於 0.01μA 的電流,啟動過程時長短於 50μs。它具有極低的電壓差、高輸出電壓精度、電流限制保護和高漣波抑制比,可以 SOT-23-3、SOT-23-5、TSOT-23-3、TSOT-23-5、SC-70-5、SC-82、MSOP-8 和 WDFN-6L 2x2 等封裝形式供貨,其輸出電壓範圍為 1.5V~5V,級差為 0.1V。
