Termination Regulator

for DDR-SDRAMs

BD35395FJ-M

General Description

Key Specifications

BD35395FJ-M is a termination regulator compatible with

JEDEC DDR1/2/3/3L-SDRAM, which functions as a linear

power supply incorporating an N-channel MOSFET and

provides a sink/source current capability up to 1A

respectively. A built-in high-speed OP-AMP specially

designed offers an excellent transient response.

Requires 3.3 volts or 5.0 volts as a bias power supply to

drive the N-channel MOSFET. Has an independent

reference voltage input pin (VDDQ) and an independent

feedback pin (VTTS) to maintain the accuracy in voltage

required by JEDEC, and offers an excellent output voltage

accuracy and load regulation.
