Overview

The LP3980 is designed for portable RF and wireless applications where performance and space are at a premium. Its performance is optimized for battery-powered systems, delivering ultralow noise and low quiescent current. In dropout, the regulator's ground current increases only slightly, further extending battery life. The LP3980 also works with low-ESR ceramic capacitors, reducing board space required for power supply applications — a critical advantage in handheld wireless devices. In shutdown mode, current consumption is less than 0.01μA, with a fast startup time of less than 50μs. Additional features include ultralow dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio.

Applications

  • Portable media players/MP3 players
  • Cellular phones and smartphones
  • LCD monitors
  • Digital camera sensors
  • Wireless network adapters

Key features

  • 1.6V to 5.5V input voltage range
  • Low dropout: 240mV at 300mA, 3.3V output
  • 300mA output current
  • High PSRR: -76dB at 1KHz
  • Standby current <1μA in shutdown
  • Ultra-fast line/load transient response
  • Current limiting protection
  • Thermal shutdown protection
  • Available in SOT23-5, SOT23, TDFN-4 packages
