Low-Voltage DDR Linear Regulators

Active: In Production.

The MAX1510/MAX17510 DDR linear regulators 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 (V_IN = 1.1V to 3.6V). The MAX1510/MAX17510 use a separate 3.3V bias supply to power the control circuitry and drive the internal n-channel MOSFETs.

The MAX1510/MAX17510 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.
