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
= 1.1V to 3.6V). The MAX1510/MAX17510 use a sepa-
rate 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 termi-
nation 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.
