Regulator IC Series for Automotive
Termination Regulator
for DDR-SDRAMs
BD35395FJ-M
General Description
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.
