LF33C - Very low drop voltage regulator

This page provides the datasheet information for the LF33C, a member of the LF33AB Very low drop voltage regulator family.

Datasheet Summary

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.
