LP2206
2×600mA,Dual Channel Ultra-Fast CMOS LDO Regulator
概述
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. 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 0.1µA in shutdown mode and has fast turn-on time less than 50µs. The other features include ultra-low dropout voltage, high feedback accuracy, current limiting protection, and high ripple rejection ratio. It is available in the 5-lead of SOT23-5 andSOT89-5 packages.
