APL5331U5C-TRL中文资料茂达电子数据手册PDF规格书

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
