BD3534FVM-TR [ROHM]

The BD3531F is a termination regulator for DDR-SDRAM with sink/source current capability up to 1.5A. It requires a 5.0V power supply bias for driving the N-channel MOSFET. By employing an independent reference voltage input (VDDQ) and a feedback pin (VTTS), it provides excellent output voltage accuracy and load regulation as required by JEDEC standards. Additionally, it includes a reference power supply output (VREF) for DDR-SDRAM or memory controllers. The VREF output remains unchanged when EN input is low, making it suitable for DDR-SDRAM in Self Refresh state. Key features include push-pull power supply for termination (VTT), reference voltage circuit (VREF), enable function, undervoltage lockout (UVLO), and thermal shutdown protector (TSD).
