FP6137D
Peak 2A Bus
Termination Regulator
Description
The FP6137D linear regulator is designed to provide
the transient peaks up to 2A sourcing or sinking
capability for DDR SDRAM bus termination appli-
cation. The output voltage can track half of input
power by two external voltage divider resistors.
The FP6137D provides current limiting in both sou-
rcing/sinking mode and thermal shutdown function
which protects the excessive heating due to high
current and high junction temperature.
The FP6137D is available in the SOP-8 (Exposed
Pad) package.

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.
Common ground pin. The VOUT sinks current to GND by lower NMOS.
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 2A.
