Outline
VRD series are high-speed, low dropout voltage, high output voltage accuracy dual regulator, low dropout to achieve High output accuracy specifications. Because dual regulator IC in the pipeline are individual separate, crosstalk can be large Greatly reduced.

Applications
 Battery powered products
  _ Phone
  _ Digital camera or camcorder
 Portable games
 Handheld instruments
