RT9030/DS9030,pdf datasheet (L

The RT9030 is a high-performance, 150mA LDO regulator, offering extremely high PSRR and ultra-low dropout. Ideal for portable RF and wireless applications with demanding performance and space requirements.
The RT9030 quiescent current as low as 25uA, further prolonging the battery life. The RT9030 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices.
The RT9030 consumes typical 0.7uA in shutdown mode and has fast turn-on time less than 40us. 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 and WDFN-6L 1.6x1.6 package.
