General Description

The LP2987/8 are fixed-output 200 mA precision LDO voltage regulators with power-ON reset delay which can be implemented using a single external capacitor.

The LP2988 is specifically designed for noise-critical applications. A single external capacitor connected to the Bypass pin reduces regulator output noise.

Using an optimized VIP™ (Vertically Integrated PNP) process, these regulators deliver superior performance:

Dropout Voltage: 180 mV @ 200 mA load, and 1 mV @ 1 mA load (typical).

Ground Pin Current: 1 mA @ 200 mA load, and 200 µA @ 10 mA load (typical).

Sleep Mode: The LP2987/8 draws less than 2 µA quiescent current when shutdown pin is held low.

Error Flag/Reset: The error flag goes low when the output drops approximately 5% below nominal. This pin also provides a power-ON reset signal if a capacitor is connected to the DELAY pin.

Precision Output: Standard product versions of the LP2987 and LP2988 are available with output voltages of 5.0V, 3.8V, 3.3V, 3.2V, 3.0V, or 2.8V, with guaranteed accuracy of 0.5% ("A" grade) and 1% (standard grade) at room temperature.

Features

  • Ultra low dropout voltage
  • Power-ON reset delay requires only one component
  • Bypass pin for reduced output noise (LP2988)
  • Guaranteed continuous output current 200 mA
  • Guaranteed peak output current > 250 mA
  • SO-8 and mini SO-8 surface mount packages
  • <2 µA quiescent current when shutdown
  • Low ground pin current at all loads
  • 0.5% output voltage accuracy ("A" grade)
  • Wide supply voltage range (16V max)
  • Overtemperature/overcurrent protection
  • -40°C to +125°C junction temperature range

Applications

  • Cellular Phone
  • Palmtop/Laptop Computer
  • Camcorder, Personal Stereo, Camera
