BD3530F

www.DataSheet4U.com DDR-SDRAM T ermination Regulator BD3530F Åú Description 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.
