300mA, 0.5% Accuracy Low Dropout, Ultra Low Noise Voltage Regulator

RT9050

The RT9050 is a high-performance, 300mA LDO regulator, offering extremely high PSRR and ultra-low dropout. The RT9050 is Ideal for portable RF and wireless applications with demanding performance and space requirements.
The RT9050 provides quiescent current to be as low as 25μA to extend the battery life. The RT9050 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, especially for hand-held wireless devices.
The RT9050 consumes typical 0.7μA in shutdown mode and has fast turn-on time to be less than 40μs. The other features include ultra-low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. The RT9050 is available in the SOT-23-5 package.
