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

 DDR-I and DDR-II Bus Termination Voltage

 SSTL-2 and SSTL-3 Termination

 Active Termination Buses

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.
