The RT9022 is designed for positive CCD bias applications with critical performance and space requirements. The RT9022 performance is optimized for battery-powered systems to deliver low noise and low quiescent current and with soft start function.

The RT9022 also works well with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications and consumes less than 1μA in shutdown mode.

The other features include ultra low dropout voltage, high output accuracy, and current limiting protection. The part is available in the SOT-23-6 and SC-70-6 packages.
