LP3982 Product details

General Description
The The LP3982 is designed for portable RF and wireless applications with demanding performance and space requirements. The LP3982 performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current. A noise bypass pin is available for further reduction of output noise. Regulator ground current increases only slightly in dropout, further prolonging the battery life. The LP3982 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The LP3982 consumes less than 0.01µA in shutdown mode and has fast turn-on time less than 50µs. The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. Available in the 5-lead of SC-70 packages.

Features
◆ Ultra-Low-Noise for RF Application
◆ 2V- 6V Input Voltage Range
◆ Low Dropout : 220mV @ 300mA
◆ 1.2V, 1.5V, 1.8V, 2.5V, 2.8V 3.0V and 3.3V Fixed
◆ 300mA Output Current, 550A Peak Current
◆ High PSSR:-80dB at 1KHz
◆ < 0.01uA Standby Current When Shutdown
◆ Available in SC-70-5 Package
◆ TTL-Logic-Controlled Shutdown Input
◆ Ultra-Fast Response in Line/Load transient
◆ Current Limiting and Thermal Shutdown Protection
◆ Quick start-up (typically 50uS)

Applications
◇ Portable Media Players/MP3 players
◇ Cellular and Smart mobile phone
◇ LCD
◇ DSC Sensor
◇ Wireless Card
