Overview

The LP3981 series low-dropout, low-power regulators offer a fast start-up and excellent line and load transient responses. A low ground current while at no load with chips enabled makes the devices attractive for battery-operate power systems. The LP3981 series also provides an active pull-down circuit to quickly discharge output load. Other features include short current limit, thermal protection and a low current consume shut-down mode. The LP3981 is available in SOT23-5 / SOT23 / DFN-4 (1mm*1mm) / DFN-6 (2mm*2mm) packages.

Applications

  • Portable Media Players/MP3 players

Key features

  • 2.5 - 5.5V Input Voltage Range
  • Low Dropout: 260mV @ 300mA Output Current, 500mA Peak Current
  • High PSRR: -63dB at 1KHz
  • <0.1uA Standby Current In Shutdown Mode
  • TTL-Logic-Controlled Shutdown Input
  • Ultra-Fast Response in Line/Load transient
