DESCRIPTION

· The NE57810 is a DDR SDRAM memory bus termination power regulator.

· It maintains an output voltage at half the RAM supply voltage.

· Capable of delivering up to ±3.5A continuously.

· Features overcurrent and overtemperature protection.

· Designed as a linear regulator, eliminating the need for external inductors or switching FETs.

· Provides fast response to load changes, reducing the need for output capacitors.

FEATURES

· Fast transient response time.

· Integrated overtemperature and overcurrent protection.

· Operates within a commercial temperature range of 0°C to +70°C.

· Minimizes external components requirement.

· Internal divider ensures termination voltage is half the memory supply voltage.

· Includes a reference output for other memory and control components.

· Supports optional external voltage reference for flexible applications.

· Compatible with DDR-I (2.5V) and DDR-II (1.8V) SDRAM systems.

APPLICATIONS

· Desktop microcomputer systems.

· Workstations and servers.

· Game machines and set-top boxes.

· Embedded systems.
