Dual-output buffer for DDR SDRAM modules
Fairchild Semiconductor has introduced a dual-output registered buffer for 184-pin, 2.5V PC200/PC266, 72bit-wide registered double data rate (DDR) SDRAM modules.
The FAN250x and FAN251x series is offered in 50, 100, 150 and 200mA versions with adjustable, 2.5, 2.6, 2.7, 2.8 2.85, 3.0 and 3.3V options.
Additional options include a bypass capacitor for enhanced noise performance, an undervoltage error flag usable as a power-good indicator and fast start enable for applications requiring fast turn-on, like cell phones.
All are supplied in the industry-standard SOT-23-5 surface-mount package and pinout.
Other features include exceptional loop stability that enables operation with all types of low cost capacitors (eg ceramic), low shutdown current (1uA), 2% accuracy over the full temperature range and thermal overload protection.
