L4931 - Very low drop voltage regulators

General Description

The L4931 is a very low drop regulator available in SO-8, DPAK and TO-92 packages and in a wide range of output voltages.

The very low drop voltage (0.4 V) and the very low quiescent current make it particularly suitable for low noise, low power applications and especially in batterypowered systems.

Key Features

  • Very low dropout voltage (0.4 V).
  • Very low quiescent current.
  • Typ. 50 µA in OFF mode, 600 µA in ON mode.
  • Output current up to 250 mA.
  • Logic controlled electronic shutdown.
  • Output voltages: 3.3; 3.5; 5;.
  • Internal current and thermal limit.
  • Only 2.2 µF for stability.
  • Available in ± 1 % (AB) or 2 % (C) selection at 25 °C.
  • Supply voltage rejection: 70 dB typ. for 5 V version.
  • Temperature range: from -.
