MIC5163

The MIC5163 is a dual regulator controller designed specifically for low voltage memory termination applications such as DDR3 and GDDR3/4/5. The MIC5163 offers a simple, low cost JEDEC compliant solution for terminating high-speed, low-voltage digital buses.

The MIC5163 controls two external N-Channel MOSFETs to form two separate regulators. It operates by switching between either the high-side MOSFET or the low-side MOSFET, depending on whether the current is being sourced to the load or being sinked by the regulator.

Designed to provide a universal solution for memory termination regardless of input voltage, output voltage, or load current; the desired MIC5163 output voltage can be externally programmed by forcing the reference voltage.

The MIC5163 operates from an input voltage as low as 0.75V up to 6V, with a second bias supply input required for operation. The MIC5163 is available in a tiny MSOP-10 package with an operating junction temperature range of -40°C to +125°C.
