General Description
The HPL5331 linear regulator is designed to provide a regulated voltage with bi-directional output current for DDR-SDRAM termination. The HPL5331 integrates two power transistors to source or sink current up to 3A. It also incorporate current-limit, thermal shutdown and shutdown control functions into a single chip. Current-limit circuit limits the short-circuit current.

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-8-P with thermal pad, TO-252- 5 and TO-263-5 Packages

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