APL5331G5 Datasheet PDF - Anpec

●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
