FP6137E
2A BUS
TERMINATION REGULATOR
Description
The FP6137E linear regulator is designed to provide
the transient peaks up to 2A sourcing or sinking
capability for DDR SDRAM bus termination
application. The output voltage can track half of input
power by two external voltage divider resistors.
The FP6137E provides current limiting in both
sourcing/sinking mode and thermal shutdown
function which protects the excessive heating due to
high current and high junction temperature.
The FP6137E is available in the SOP-8 (Exposed
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, DDR-II, and DDR-III Bus Termination
Voltage
● SSTL-2 and SSTL-3 Termination
● Active Termination Buses
