General Description

The AS1376 is a dual supply rail linear regulator designed to deliver 1A of load current while consuming only 67μA (typ) of ground current. In the typical post regulation application VBIAS is directly connected to the main input supply (range 2.5V - 5.5V) and Vin is supplied by the output voltage of a host DC-DC converter (range 0.7V - 4.5V).

This product suits for the following applications:

  • Powering cordless and mobile phones
  • MP3 players
  • CD and DVD players
  • PDAs
  • Handheld computers
  • Digital cameras
  • Any other hand-held and/or battery-powered device
