KF33B - Very low drop voltage regulators

General Description

The KFxx series are very low drop regulators available in SO-8 package and in a wide range of output voltages.

suitable for low noise, low power applications and specially in battery powered systems.

Key Features

  • Very low dropout voltage (0.4 V).
  • 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; 2.5; 3.3; 4; 5; 8 V.
  • Internal current and thermal limit.
  • Only 2.2 µF for stability.
  • Available in ± 2 % accuracy at 25 °C.
  • Supply voltage rejection: 70 db (typ. ).
  • Temperature range: -40 to 125 °C.
