MAX1510ETB
Low-Voltage DDR Linear Regulator
General DescriptionThe 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 (VIN= 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.

MAX1510
Low-Voltage DDR Linear Regulator
Detailed DescriptionThe MAX1510 is a low-voltage, low-dropout DDR termi-
nation linear regulator with an external bias supply
input and a buffered reference output (see Figures 1
and 2). VCCis powered by a 2.7V to 3.6V supply that is
commonly available in laptop and desktop computers.
The 3.3V bias supply drives the gate of the internal
pass transistor, while a lower voltage input at the drain
of the transistor (IN) is regulated to provide VOUT. By
using separate bias and power inputs, the MAX1510
can drive an n-channel high-side MOSFET and use a
lower input voltage to provide better efficiency.
The MAX1510 regulates its output voltage to the volt-
age at REFIN. When used in DDR applications as a
termination supply, the MAX1510 delivers 1.25V or
0.9V at 3A peak (typ) from an input voltage of 1.1V to
3.6V. The MAX1510 sinks up to 3A peak (typ) as
required in a termination supply. The MAX1510 pro-
vides shoot-through protection, ensuring that the
source and sink MOSFETs do not conduct at the same
time, yet produces a fast source-to-sink load transient.
