BD3530F

DDR-SDRAM Termination Regulator

BD3530F is a regulator developed as termination

power supply of standard DDR-SDRAM that is

used for PC.

Industry's highest speed of transient response

characteristic is realized. The built-in FET can sink

and source load current of 3A(max.)

Waveform quality when data is transferred at high

speed can't be deteriorated.

BD3530F meets the bus line standards SSTL-2 of

DDR-SDRAM.

High-reliability can be realized for any applications

using DDR-SDRAM.
