General Description

The LP3990 is designed for portable RF and wireless applications with demanding performance and space requirements. The LP3990 performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current. The LP3990 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The LP3990 consumes less than 0.01μA 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 1mm×1mm X2SON packages.
