The linear regulators MAX1510/MAX17510 DDR source and sink up to 3A peak (typ) using internal n-channel MOSFETs. These linear regulators deliver an accurate 0.5V to 1.5V output from a low-voltage power input (VIN = 1.1V to 3.6V). They use a separate 3.3V bias supply to power the control circuitry and drive the internal n-channel MOSFETs.

Application and uses of MAX1510/MAX17510 are in Active Termination Buses, Chipset/RAM Supplies as Low as 0.5V, DDR Memory Termination, Graphics Processor Core Supplies and in Notebook and Desktop Computers.

They also provide current and thermal limits to prevent damage to the linear regulator. Additionally, the MAX1510/MAX17510 generate a power-good (PGOOD) signal to indicate that the output is in regulation. During startup, PGOOD remains low until the output is in regulation for 2ms (typ). The internal soft-start limits the input surge current.

The MAX1510/MAX17510 power the active-DDR termination bus that requires a tracking input reference. The MAX1510/MAX17510 can also be used in low-power chipsets and graphics processor cores that require dynamically adjustable output voltages. The MAX1510/MAX17510 are available in a 10-pin, 3mm x 3mm thin DFN package.

The Key features are Internal Power MOSFETs with Current Limit (3A typ) , Fast Load-Transient Response , External Reference Input with Reference Output Buffer , 1.1V to 3.6V Power Input , ±15mV (max) Load-Regulation Error. MAX1510/MAX17510 also have Thermal-Fault Protection , Shutdown Input , Power-Good Window Comparator with 2ms (typ) Delay . They come in Small, Low-Profile 10-Pin, 3mm x 3mm TDFN Package  and as Ceramic or Polymer Output Capacitors
