LF40AB - Very low drop voltage regulators

Description

The LF00 series are very Low Drop regulators available in PENTAWATT, TO-220, TO-220FP, DPAK and PPAK package and in a wide range of output voltages.

Features

  • Very low dropout voltage (0.45V).
  • Very low quiescent current (TYP. 50 µA in OFF mode, 500 µA in ON mode).
  • Output current up to 500 mA.
  • Logic-controlled electronic shutdown.
  • Output voltages of 1.5; 1.8; 2.5; 2.7; 3; 3.3; 3.5; 4; 5; 6; 8; 8.5; 9; 12V.
  • 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: 80db (typ. ).
  • Temperature range: -40 to 125°C.
