RT9194GE

General Description
The RT9193 is designed for portable RF and wireless applications with demanding performance and space requirements.
The RT9193 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 RT9193 also 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.
Features Ultra-Low-Noise for RF Application Ultra-Fast Response in Line/Load Transient Quick Start-Up (Typically 50μs) < 0.01μA Standby Current When Shutdown Low Dropout : 220mV @ 300mA Wide Operating Voltage Ranges : 2.5V to 5.5V TTL-Logic-Controlled Shutdown Input Low Temperature Coefficient Current Limiting Protection
