Preliminary Datasheet

LP3989

600mA,Ultra-low noise, Small Package,

Ultra-Fast CMOS LDO Regulator

General Description

Features

The LP3989 is designed for portable RF and wireless

applications with demanding performance and space

requirements. The LP3989 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 LP3989 also works with low-ESR

ceramic capacitors, reducing the amount of board

space necessary for power applications, critical in

hand-held wireless devices. The LP3989 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

packages.
