Preliminary Datasheet LP3983H 600mA,Ultra-low noise, Small Package Ultra-Fast CMOS LDO Regulator General Description The LP3983H is designed for portable RF and wireless applications with demanding performance and space requirements. The LP3983H performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current. A noise bypass pin is available for further reduction of output noise. Regulator ground current increases only slightly in dropout, further prolonging the battery life. The LP3983H also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The LP3983H consumes less than 0.01µA in shutdown mode and has fast turn-on time less than 50µs.
