RT9030-18GQW Product Details

General Description 

The RT9030-18GQW 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 RT9030-18GQW quiescent current as low as 25μA, further prolonging the battery life. The RT9030-18GQW also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in handheld wireless devices. 

The RT9030-18GQW consumes typical 0.7μA in shutdown mode and has fast turn-on time less than 40μs. 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.
