Termination Regulator for DDR-SDRAMs
BD3532F
General Description
BD3532F is a termination regulator that complies with
JEDEC requirements for DDR-SDRAM. This linear
power supply uses a built-in N-channel MOSFET and
high-speed OP-AMPS specially designed to provide
excellent transient response. It has a sink/source
current capability up to 3A and has a power supply
bias requirement of 5.0V for driving the N-channel
MOSFET. By employing an independent reference
voltage input (VDDQ) and a feedback pin (VTTS), this
termination regulator provides excellent output voltage
accuracy and load regulation as required by JEDEC
standards. Additionally, BD3532F has a reference
power supply output (VREF) for DDR-SDRAM or for
memory controllers. Unlike the VTT output that goes to
“Hi-Z” state, the VREF output is kept unchanged when
EN input is changed to “Low”, making this IC suitable
for DDR-SDRAM under “Self Refresh” state.
