FP6137A/B
3A/2A Bus
Termination Regulator
Description
Features
The FP6137A/B linear regulator is designed to
provide the transient peaks up to 3A/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.
3A/2A Source or Sink Current
Power MOSFET Integrated
Low Output Voltage Offset
Current Limit Protection
Thermal Shutdown Protection
Adjusted Output by External Resistors
Shutdown for Standby or Suspend Mode
SOP-8, TO-252-5 and TO-263-5 Packages
RoHS Compliant
The FP6137A/B provides current limit in both
sourcing/sinking mode and thermal shutdown
function which protects the excessive heating due to
high current and high junction temperature.
The FP6137A are available in SOP-8 (exposed pad),
TO-252-5 and TO-263-5 packages. The FP6137B
are available in the SOP-8 (fused), SOP-8 (exposed
pad) and TO-252-5 packages.
Applications

Functional Pin Description
Pin Name
Pin Function
Power Input Pin. VIN is the input power supply used to create the external reference voltage for regulating
VOUT. VIN sources current to VOUT by upper NMOS.
VIN
GND
Common Ground Pin. The VOUT sinks current to GND by lower NMOS.
VCNTL
REFEN
VOUT
Power Input Pin. The VCNTL power supplies the internal control circuitry and gate drive voltage.
Chip Enable, and Input Reference Voltage Pin. The reference voltage is half of the VIN power by two external
voltage divide resistors.
Regulator Output Pin. VOUT voltage tracks the REFEN voltage and is capable of sourcing or sinking current up
to peak 3A.
