APL5337

APL5337 Source and Sink, 2A, Fast Transient Response Linear Regulator Features General Description Provide Bi-direction Current - Sourcing or Sinking Current Up to 2A Built-in Soft-Start Power-On-Reset Monitoring on VCNTL Pins Fast Transient Response Stable with Ceramic Output Capacitors ±10mV High System Output Accuracy Over Load and Temperature Ranges Adjustable Output Voltage by External Resistors Current-Limit Protection On-Chip Thermal Shutdown Shutdown for Standby or Suspend Mode Simple SOP-8 and SOP-8 with Exposed Pad (SOP-8P) Packages Lead Free and Green Devices Available (RoHS Compliant) Applications DDRII/III/IV SDRAM Termination Voltage Motherboard and VGA Card Power Supplies Setop Box Low Power DDR3 DDRIII/IV The APL5337 linear regulator is designed to provide a regulated voltage with bi-direction output current for DDRSDRAM termination voltage. The APL5337 integrates two power transistors to source or sink load current up to 2A. It also features internal soft-start, current-limit, thermal shutdown and enable control functions into a single chip. The internal soft-start controls the rising rate of the output voltage to prevent inrush current during start-up. The current-limit circuit detects the output current and limits the current during short-circuit or current overload conditions. The on-chip thermal shutdown provides thermal protection against any combination of overload that would create excessive junction temperatures. T...
