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
