LP2989LV - 500-mA Ultra Low-Dropout Regulator

General Description

The LP2989LV is a fixed-output 500-mA precision LDO regulator designed for use with ceramic output capacitors.

Output noise can be reduced to 18 μV (typical) by connecting an external 10-nF capacitor to the bypass pin.

Key Features

  • 1 2.1-V to 16-V Input Voltage Range.
  • Ultra-Low Dropout Voltage.
  • 500-mA Continuous Output Current.
  • Very Low Output Noise With External Capacitor.
  • < 0.8-µA Quiescent Current When Shut Down.
  • Low Ground Pin Current at All Loads.
  • 0.75% Output Voltage Accuracy (A Grade).
  • High Peak Current Capability (800-mA typical).
  • Overtemperature and Overcurrent Protection.
  • 40°C to +125°C Junction Temperature Range 2.
