General Description

The LP2992 is a 250 mA, fixed-output voltage regulator designed to provide ultra low-dropout and low noise in battery powered applications.

Using an optimized VIP™ (Vertically Integrated PNP) process, the LP2992 delivers unequalled performance in all specifications critical to battery-powered designs:

Dropout Voltage: Typically 450 mV @ 250 mA load, and 5 mV @ 1 mA load.

Ground Pin Current: Typically 1500 µA @ 250 mA load, and 75 µA @ 1 mA load.

Enhanced Stability: The LP2992 is stable with output capacitor ESR as low as 5 m, which allows the use of ceramic capacitors on the output.

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

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

Precision Output: 1% tolerance output voltages available (A grade).

Low Noise: By adding a 10 nF bypass capacitor, output noise can be reduced to 30 µV (typical).

Multiple voltage options, from 1.5V to 5.0V, are available as standard products. Consult factory for custom voltages.

Features

  • Ultra low dropout voltage
  • Guaranteed 250 mA output current
  • Smallest possible size (SOT-23, LLP package)
  • Requires minimum external components
  • Stable with low-ESR output capacitor
  • <1 µA quiescent current when shut down
  • Low ground pin current at all loads
  • Output voltage accuracy 1% (A Grade)
  • High peak current capability
  • 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
