General Description

The MAX1510 DDR linear regulator sources and sinks up

to 3A peak (typ) using internal n-channel MOSFETs. This

linear regulator delivers an accurate 0.5V to 1.5V output

from a low-voltage power input (V

= 1.1V to 3.6V). The

MAX1510 uses a separate 3.3V bias supply to power the

control circuitry and drive the internal n-channel

MOSFETs.

The MAX1510 provides current and thermal limits to

prevent damage to the linear regulator. Additionally,

the MAX1510 generates a power-good (PGOOD) signal

to indicate that the output is in regulation. During start-

up, PGOOD remains low until the output is in regulation

for 2ms (typ). The internal soft-start limits the input

surge current.

The MAX1510 powers the active-DDR termination bus

that requires a tracking input reference. The MAX1510

can also be used in low-power chipsets and graphics

processor cores that require dynamically adjustable

output voltages. The MAX1510 is available in a 10-pin

3mm x 3mm thin DFN package.
