Product Overview

The L4931CZ33-AP is a very low drop Voltage Regulator with inhibit function. The very low drop voltage (0.4V) and the very low quiescent current make it particularly suitable for low noise, low power applications and especially in battery-powered systems. A TTL compatible shutdown logic control function is available in PPAK and SO-8 packages. This means that when the device is used as a local regulator, a part of the board can be put in standby mode, decreasing the total power consumption. It requires only a 2.2μF capacitor for stability allowing space.
  • Very low dropout voltage (0.4V)
  • Very low quiescent current
  • Typical 50μA in OFF mode and 600μA in ON mode
  • Output current up to 250mA
  • Logic controlled electronic shutdown
  • Internal current and thermal limit
  • Only 2.2μF for stability
  • Supply voltage rejection of 70dB typical for 5V version
