The RT9020 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 quiescent current is as low as 25mA, further prolonging the battery life. The RT9020 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 consumes typical 0.7mA in shutdown mode and has fast turn-on time less than 70ms (without C_SS). 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.
