General  Description
The APL5331 linear  regulator  is  designed  to  provide  a regulated  voltage  with  bi-directional   output  current  for DDR-SDRAM  terminati on  voltage.  The APL5331  integrates  two  power  transistors  to  source  or sink  current up to 3A. It also incorporates current-limit, thermal shut down and shutdown control functions into a single chip.

FEATUREs
• Provide Bi-direction Current
  - Sourcing or Sinking Current up to 3A
• 1.25V/0.9V Output for DDR I/II Applications
• Fast Transient Response
• High Output Accuracy
  - ±20mV over Load, VOUT Offset and Temperature
• Adjustable Output Voltage by External Resistors
• Current-Limit Protection
• On-Chip Thermal Shutdown
• Shutdown for Standby or Suspend Mode
• Simple SOP-8, SOP-8P with thermal pad, TO-252-5 and TO-263-5 Packages
• Lead Free and Green Devices Available (RoHS Compliant)

APPLICATIONs
• DDR  I/II  SDRAM  T ermination
• SSTL-2/3 Termination Voltage
• Applications  Requiring  the  Regulator  with Bi-directional  3A  Current  Capability
