General Description

The LP3985 is designed for portable RF and wireless applications with demanding performance and space requirements. The LP3985 performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current. The LP3985 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. 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 SOT23-3 and SOT89-3 packages.
