General Description

The LP2980 is a 50 mA, fixed-output voltage regulator designed specifically to meet the requirements of battery-powered applications.

Using an optimized VIP™ (Vertically Integrated PNP) process, the LP2980 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 an absolute minimum board space.

Minimum Part Count. Requires only 1 µF of external capacitance on the regulator output.

Precision Output. 0.5% tolerance output voltages available (A grade).

5.0V, 3.3V, and 3.0V versions available as standard products.

Features

  • Ultra low dropout voltage
  • Output voltage accuracy 0.5% (A Grade)
  • Guaranteed 50 mA output current
  • Smallest possible size (SOT-23, micro SMD package)
  • Requires only 1 µF external capacitance
  • < 1 µA quiescent current when shutdown
  • Low ground pin current at all load currents
  • High peak current capability (150 mA typical)
  • Wide supply voltage range (16V max)
  • Fast dynamic response to line and load
  • Low ZOUT over wide frequency range
  • Overtemperature/overcurrent protection
  • -40°C to +125°C junction temperature range

Applications

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