ROHM BD3538F handbook

BD3538F / HFN is a termination regulator compatible with JEDEC DDR-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. Also has a reference power supply output pin (VREF) for DDR-SDRAM or a memory controller. When EN pin turns to “Low”, VTT output becomes “Hi-Z” while VREF output is kept unchanged, compatible with “Self Refresh” state of DDR-SDRAM.
