The RT9053A is a high performance, 400mA LDO regulator and ultra low dropout. The quiescent current is as low as 42μA, further prolonging the battery life. The RT9053A also works with low ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in handheld wireless devices.<br />The RT9053A consumes typically 0.7μA in shutdown mode. The other features include low dropout voltage, high output accuracy, and current limiting protection. The RT9053A is available in SOT-23-5 and WDFN-6L 2x2 packages.</div>
