LP3981 - 300-mA Ultra-Low-Dropout CMOS Voltage Regulator

General Description

Performance of the LP3981 device is optimized for battery-powered systems to deliver ultra-low-noise, extremely low dropout voltage, and low quiescent current.

Regulator ground current increases only slightly in dropout, further prolonging the battery life.

Key Features

  • 1 2.5-V to 6-V Input Range.
  • 300-mA Output Current.
  • 60-dB PSRR at 1 kHz.
  • ≤ 1-μA Quiescent Current When Shut Down.
  • Fast Turnon Time: 120 μs (typical) with.
