General Description

The LP2982 is a 50 mA, fixed-output voltage regulator designed to provide ultra low dropout and lower noise in battery powered applications.

Using an optimized VIP™ (Vertically Integrated PNP) process, the LP2982 delivers unequaled performance in all specifications critical to battery-powered designs:

Dropout Voltage: Typically 120 mV @ 50 mA load, and 7 mV @ 1 mA load.

Ground Pin Current: Typically 375 µA @ 50 mA load, and 80 µA @ 1 mA load.

Sleep Mode: Less than 1 µA quiescent current when on/off pin is pulled low.

Smallest Possible Size: SOT-23 and micro SMD packages use absolute minimum board space.

Precision Output: 1.0% tolerance output voltages available (A grade).

Low Noise: By adding an external bypass capacitor, output noise can be reduced to 30 µV (typical).

Ten output voltage versions, from 2.5V to 5.0V, are available as standard products.

Features

  • Ultra low dropout voltage
  • Guaranteed 50 mA output current
  • Typical dropout voltage 180 mV @ 80 mA
  • Smallest possible size (SOT-23, micro SMD package)
  • Requires minimum external components
  • < 1 µA quiescent current when shutdown
  • Low ground pin current at all loads
  • Output voltage accuracy 1.0% (A Grade)
  • High peak current capability (150 mA typical)
  • Wide supply voltage range (16V max)
  • Low ZOUT 0.3 typical (10 Hz to 1 MHz)
  • Overtemperature/overcurrent protection
  • -40°C to +125°C junction temperature range
  • Custom voltages available

Applications

  • Cellular Phone
  • Palmtop/Laptop Computer
  • Personal Digital Assistant (PDA)
  • Camcorder, Personal Stereo, Camera
