MP20073 1.3-6V 2A, 1.3V–6.0V DDR Memory Termination Regulator MSOP8

The MPS MP20073 is a 2A, 1.3V–6.0V DDR Memory Termination Regulator. It operates from a 1.3 V to 6 V input and is rated for 2 A. It is supplied in a MSOP8 package.

The MP20073 integrates the DDR memory termination regulator with the output voltage (VTT) and a buffered VTTREF outputs is a half of VREF.

Design Notes

Dissipation is (VIN − VOUT) × IOUT. Check it against the package thermal resistance at the real ambient temperature before committing to the full rated current.
Some low-noise LDOs require a minimum output capacitor ESR for loop stability — read the stability section before substituting a ceramic part.
Add a bypass capacitor on the reference pin where provided; it sets the output noise floor.
PSRR falls as the input-to-output differential shrinks, so headroom matters at low VIN.
