Termination Regulator for DDR-SDRAMs - BD35390FJ

BD35390FJ is a termination regulator that complies with JEDEC requirements for DDR1/2/3-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 1A and has a power supply bias requirement of 3.3V to 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.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
