LP2206
2×600mA,Dual Channel Ultra-Fast CMOS LDO Regulator
概述
The LP3992 is designed for portable RF and wireless applications with demanding performance and space requirements. The LP3992 performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current. The LP3992 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The LP3992 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 output accuracy, current limiting protection, and high ripple rejection ratio. It is available in the 5-lead of SOT23-5 and TSOT23-5 packages.
