Description

The LFXX is a very low drop regulator available in TO-220, TO-220FP, DPAK and PPAK packages and in a wide range of output voltages. The low drop voltage (0.45 V) and low quiescent current make it particularly suitable for low-noise, low-power applications and especially in batterypowered systems.

Key Features

  • Very low-dropout voltage (0.45 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
  • Automotive grade product: 1.8 V, 2.5 V, 3.3 V, 5.0 V, 8.0 V, 8.5 V VOUT in DPAK and PPAK packages
  • Internal current and thermal limit
  • Only 2.2 µF for stability
  • Available in ±1% (AB), ±1.5% (AC) or ±2% (C) selection at 25 °C
  • Supply voltage rejection: 80 db (typ.)
  • Temperature range: from -40 to 125 °C
