ROHM Semiconductor USA, LLC Special Purpose Regulators BD3533F-E2

BD3533F-E2 is a termination regulator designed for DDR-SDRAM applications, compliant with JEDEC standards. It operates within a termination input voltage range of 1.0V to 5.5V and a VCC input voltage range of 2.7V to 5.5V. The device features a built-in N-channel MOSFET and high-speed operational amplifiers, providing a sink/source current capability of up to 1A, with a maximum output current of 3A for the BD3533F variant. The regulator includes a reference voltage output (VREF) that remains stable during low enable states, making it suitable for DDR-SDRAM in self-refresh modes. Additional features include under-voltage lockout (UVLO), thermal shutdown protection (TSD), and compatibility with dual-channel DDR-2 configurations. The operating temperature range is specified from -20¬8C to +100¬8C, and the device is available in multiple package types, including SOP8, MSOP8, and HSON8.
