  • 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
  • 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
