LD2985 - Very low drop and low noise voltage regulator

General Description

The LD2985 is a 150 mA fixed output voltage regulator.

The ultra low drop voltage and the low quiescent current make them particularly suitable for low noise, low power applications, and in battery powered systems.

In sleep mode quiescent current is less than 1 µA when INHIBIT pin is pulled low.

Key Features

  • Very low dropout voltage (280 mV at 150 mA and 7 mV at 1 mA load).
  • Very low quiescent current (2 mA typ. at 150 mA load and 80 µA at no load).
  • Output current up to 150 mA.
  • Logic controlled electronic shutdown.
  • Output voltage of 1.8, 2.5, 2.8, 3, 3.1, 3.3, 5 V.
  • Internal current and thermal limit.
  • Low output noise voltage 30 µVrms.
  • Small package SOT23-5L.
  • Temperature range: - 40 °C to 125 °C Datasheet - production d.
