POWER LP1116 800ma,ultra-low noise ldo regulator Datasheet

Preliminary Datasheet
LP1116
800mA,Ultra-low Noise LDO Regulator
General Description
Features
The LP1116 is designed for portable applications with

Ultra-Low-Noise for RF Application
demanding performance and space requirements. The

2.5V- 6.5V Input Voltage Range
LP1116 performance is optimized for battery-powered

Low Dropout : 480mV @ 600mA

Ultra-Fast Response in Line/Load Transient

Current Limiting and Thermal Shutdown
Protection
systems to deliver ultra low noise and low quiescent
current. Regulator ground current increases only
slightly in dropout, further prolonging the battery life.
The LP1116 also works with low-ESR ceramic
capacitors, reducing the amount of board space
necessary for power applications, critical in hand-held
