RT9013概述
The RT9013 is a high-performance, 500mA LDO regulator,offering extremely high PSRR and ultra-low dropout. Ideal for portable RF and wireless applications with demanding performance and space requirements.The RT9013 quiescent current as low as 25μA, further prolonging the battery life. The RT9013 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The RT9013 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 SOT-23-5, SC-70-5 and WDFN-6L 2×2 package.
