1 / 7 page  LP3985-00 May.-2018 Email: marketing@lowpowersemi.com www.lowpowersemi.com Page 1 of 7 Preliminary Datasheet LP3985 300mA,Ultra-low noise, Small Package Ultra-Fast CMOS LDO Regulator 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.
