3A Adjustable Output Voltage LDO Regulator

RT9033

The RT9033 is a low dropout linear regulator designed for high output current applications with critical performance. The IC responds very fast to step changes in load, which is suitable for low voltage microprocessor applications.
The RT9033 uses an internal P-MOSFET as the pass device, which does not cause extra GND current in heavy load and dropout condition. The shutdown mode of low operation current makes the IC suitable for power-saving systems.
The RT9033 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, current limiting protection and over temperature protection. The RT9033 is available in the TO-263-5 package.
