FP6137C

fitipower integrated technology lnc. FP6137C 2A BUS TERMINATION REGULATOR Description The FP6137C linear regulator is designed to provide the transi ent peaks up to 2A sou rcing or sin king capability for DDR SDRA M bus termination application. T he output volt age ca n tra ck half of input power by two external voltage divider resistors. The FP61 37C provides current limiting in both sourcing/sinking mode a nd th ermal shutdown fun ction which prote cts the excessive heating due to high current and high junction temperature. The FP6137 C is availabl e in the SOP-8 (Expose d Pad) package. Features ● 2A Source or Sink Current ● Power MOSFET Integrated ● Low Output Voltage Offset ● Current Limiting Protection ● Thermal Shutdown Protection ● Adjusted Output by External Resistors ● Shutdown for Standby or Suspend Mode ● RoHS Compliant Applications ● DDR-I and DDR-II Bus Termination Voltage ● SSTL-2 and SSTL-3 Termination ● Active Termination Buses Pin Assignments SP Package (SOP-8) VIN GND REFEN VOUT 1 2 3 4 GND Ordering Information FP6137C□□□ TR: Tape/Reel Blank: Tube P: Pb Free with Commercial Standard (RoHS Compliant) Package Type SP: SOP-8 (Exposed Pad) 8 7 6 5 NC NC VCNTL NC Figure 1.
