Features & Applications

The LD2980CM33TR is a low drop-voltage and the ultra low quiescent current make them suitable for low noise, low power applications and in battery poweredsystems. The quiescent current in sleep mode is less than 1 μA when the INHIBIT pin is pulled low.

A shutdown logic control function is available on pin n° 3 (TTL compatible). This means that when the device is used as local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption. The LD2980 is designed to work with low ESR ceramic capacitors

Features:

  • Stable with low ESR ceramic capacitors
  • Ultra low dropout voltage (0.12 V typ. at 50 mA load, 7 mV typ. at 1 mA load)
  • Very low quiescent current (80 μA typ. at no load in on mode; max 1 μA in off mode)
  • Guaranteed output current up to 50 mA
  • Logic-controlled electronic shutdown
  • Output voltage of 1.8; 3.0; 3.3; 3.6; 5.0 V
  • Internal current and thermal limit
  • ±0.5% Tolerance output voltage available (A version)
  • Output low noise voltage 160 μVRMS
  • Temperature range: -40 to 125 °C
  • Smallest package SOT23-5L and SOT-89
  • Fast dynamic response to line and load changes

Applications:

  • Cellular phone
  • Laptop computer
  • Personal digital
  • Assistant (PDA)
  • Personal stereo
  • Camcorder
  • Camera
