The RT9020-25GU5 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 RT9020-25GU5 quiescent current is as low as 25μA, further prolonging the battery life. The RT9020-25GU5 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The RT9020-25GU5 consumes typical 0.7μA in shutdown mode and has fast turn-on time less than 70μs (without CSS). The other features include ultra-low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. Tiny packages SOT-23-5 and SC-70-5 are available.
