LF80C - Very low drop voltage regulator

Download the LF80C datasheet PDF. This datasheet also covers the LF80AB variant, as both devices belong to the same very low drop voltage regulator family and are provided as variant models within a single manufacturer datasheet.

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.

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.
  • Output voltages of 1.5; 1.8; 2.5; 3.3; 4.7; 5; 6; 8; 8.5; 9; 12 V.
  • 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) select.
