Preliminary Datasheet

LP3986

300mA,Ultra-low Noise LDO Regulator

General Description

Features

The LP3986 is designed for portable applications with

demanding performance and space requirements. The

LP3986 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 LP3986 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. Available in

the 3-lead of SOT23-3 and SOT89-3 packages

 Ultra-Low-Noise for RF Application

 2.5V- 6V Input Voltage Range

 Low Dropout : 220mV @ 300mA

 Ultra-Fast Response in Line/Load Transient

 Current Limiting and Thermal Shutdown
