General Description

The LP2967 is a 150 mA, dual 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 LP2967 delivers unequalled performance in all specifications critical to battery powered designs:

Dropout Voltage: Typically 240 mV at 150 mA load, and 6 mV at 1 mA load for each output.

Ground Pin Current: Typically 1 mA at 150 mA load, and 200 µA at 1 mA load for each output.

Enhanced Stability: The LP2967 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 2 µA quiescent current when SD pins are pulled low.

Smallest Possible Size: micro SMD package uses absolute minimum board space.

Precision Output: 1.25% tolerance.

Low Noise: By adding a 100 nF bypass capacitor, output noise can be reduced to 30 µV (typical).

Multiple voltage options, from 1.8V to 5.0V, are available. Consult factory for custom voltages.

Features

  • Ultra low drop-out voltage
  • Guaranteed 150mA output current, 300 mA peak
  • Smallest possible size (micro SMD package)
  • Requires minimum external components
  • Stable with 2.2 µF tantalum or ceramic capacitor
  • Output voltage accuracy ±1%
  • < 2 µA quiescent current when shut down
  • Wide supply voltage range (16V max.)
  • Low ZOUT: 0.3 typical (10 Hz to 1 MHz)
  • Over temperature/over current protection
  • -40°C to +125°C junction temperature range
  • Custom voltages available

Applications

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