BD3533EKN-E2

The ROHM Semiconductor BD3533EKN-E2 is a specialized linear power supply regulator IC designed for DDR-SDRAM termination. It functions as a sink/source current regulator, offering a capability of up to 1A for the BD3533 series.

This device operates with an input voltage range from 2.7V to 5.5V and features an operating temperature range of -20°C to 100°C. It incorporates an independent reference voltage input pin (VDDQ) and feedback pin (VTTS) to maintain accuracy required by JEDEC standards, ensuring excellent output voltage accuracy and load regulation. The BD3533EKN-E2 also includes a reference power supply output pin (VREF) suitable for DDR-SDRAM or memory controllers.

Packaged in a 20-HQFNV (4.2x4.2) format, the BD3533EKN-E2 is designed for surface mounting. Its features include an enabler and an undervoltage lockout (UVLO), making it compatible with DDR I/II memory systems and supporting features like 'Self Refresh' state when the EN pin is low.

This regulator is ideal for power supply applications in DDR I/II SDRAM systems, providing stable and accurate voltage regulation for memory interfaces.
