General description
The NE57810 DDR termination regulator maintains an output voltage (DDR reference bus voltage) that is half the RAM supply voltage. It is capable of providing up to +- 3.5 A for sustained periods. Overcurrent limiting protects the NE57810 from inrush currents at start-up. Overtemperature shutdown protects the device in extreme temperature situations.
The package is thermally robust for flexibility of thermal design. The NE57810 is a linear regulator so no external inductors or switching FETs are necessary. Fast response to load changes reduces the need for output capacitors.
Features
- Fast transient response time
- Overtemperature protection
- Overcurrent protection
- Commercial (0 Cel to +70 Cel) temperature range
- Reduced need for external components (switching FETs, inductors, decoupling capacitors)
- Internal divider maintains termination voltage at half the memory supply voltage
- Reference out for other memory and control components
- Optional external voltage reference in for flexible application
- Compatible with DDR-I (VDD = 2.5 V) or DDR-II (VDD = 1.8 V) SDRAM systems
