General Description

The LP2985LV is a 150 mA, fixed-output voltage regulator designed to providehigh performance and low noise in applications requiring output voltages < 2.3V.

Using an optimized VIP™ (Vertically Integrated PNP) process, the LP2985LV delivers unequalled performance in all specifications critical to battery-powered designs:

Ground Pin Current: Typically 825 µA @ 150 mA load, and 75 µA @ 1 mA load.

Enhanced Stability: The LP2985LV 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: micro SMD package uses 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).

Features

  • Guaranteed 150 mA output current
  • Smallest possible size (micro SMD)
  • 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
