RT9198T
300mA, Thermal Folded Back CMOS LDO Regulator
General Description
Features
The RT9198T is designed for portable RF and wireless z Short Circuit Thermal Folded Back Protection
applications with demanding performance and space z Low-Noise for RF Application
requirements. The RT9198T performance is optimized for z Fast Response in Line/Load Transient
battery-powered systems to deliver ultra low noise and z Quick Start-Up (Typically 50us)
low quiescent current. Regulator ground current increases z < 0.01uA Standby Current When Shutdown
only slightly in dropout, further prolonging the battery life. z Low Dropout : 220mV @ 300mA
The RT9198T also works with low-ESR ceramic capacitors, z Wide Operating Voltage Ranges : 2.5V to 5.
