RT9193 是专为满足便携式设备的射频和无线应用的苛刻性能与空间要求而设计。RT9193 在1mA的负载时DROPOUT电压仅为1mV，在150mA负载时　DROPOUT电压低于200mV。RT9193 还具有极低的静态电流（典型值＜100uA），当ENPIN＝Low时更可以使晶片的Standby电流低于1uA，延长电池的工作时间。外加Bypass电容可以极大的抑制杂讯，PSRR高达70dB（Typ）。RT9193具有过流保护、温度保护功能。输出电压共有　3.3V、2.8V、2.5V、1.8V、1.5V。封装形式：SOT-23-5
The RT9193 is designed for portable RF and wireless applications with demanding performance and space requirements. The RT9193 erformance 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 lso 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. The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. Available in the SC-70-5, SOT-23-5, TSOT-23-5, WDFN-6L 2×2 and MSOP-8 packages.
