FP6137F
3A BUS
TERMINATION REGULATOR
Description
The FP6137F linear regulator is designed to provide
the transient peaks up to 3A 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 FP6137F 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 FP6137F is available in SOP-8 (Exposed Pad)
package.
Features
● Peak 3A Source or Sink Current
● Power MOSFET Integrated
● Low Output Voltage Offset
● Built-in Soft-start
● Current Limiting Protection
● Thermal Shutdown Protection
● Adjustable Output by External Resistors
● Shutdown for Standby or Suspend Mode
● RoHS Compliant
Applications
● DDR-I, DDR-II, DDR-III ,and DDR-IIIL Bus
Termination Voltage
● SSTL-2 and SSTL-3 Termination
● Active Termination Buses
