Low-Voltage DDR Linear Regulators
General Description
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 (VIN =
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 devices 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.

Typical Operating Characteristics (continued)
Detailed Description
The MAX1510/MAX17510 are low-voltage, low-dropout
DDR termination linear regulators with an external bias
supply input and a buffered reference output (see Figures
1 and 2). VCC is 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 sep-
arate bias and power inputs, the MAX1510/MAX17510
can drive an n-channel high-side MOSFET and use a
lower input voltage to provide better efficiency.
The MAX1510/MAX17510 regulate their output voltage
to the voltage at REFIN. When used in DDR applica-
tions as a termination supply, the MAX1510/MAX17510
deliver 1.25V or 0.9V at 3A peak (typ) from an input volt-
age of 1.1V to 3.6V. The MAX1510/MAX17510 sink up
to 3A peak (typ) as required in a termination supply. The
MAX1510/MAX17510 provide shoot-through protection,
ensuring that the source and sink MOSFETs do not con-
duct at the same time, yet produce a fast source-to-sink
load transient.Figure 1. Standard Application Circuit
PINNAMEFUNCTIONREFOUTBufered Reference Output. The output of the unity-gain reference input bufer sources and sinks over
5mA. Bypass REFOUT to AGND with a 0.33µF or greater ceramic capacitor.VCCAnalog Supply Input. Connect to the system supply voltage (+3.3V). Bypass VCC to AGND with a 1µF or
greater ceramic capacitor.AGNDAnalog Ground. Connect the backside pad to AGND.REFINExternal Reference Input. REFIN sets the output regulation voltage (VOUTS = VREFIN).PGOOD
Open-Drain Power-Good Output. PGOOD is low when the output voltage is more than 150mV (typ) above
or below the regulation point, during soft-start, and when shut down. 2ms after the output reaches the
regulation voltage during startup, PGOOD becomes high impedance.OUTSOutput Sense Input. The OUTS regulation level is set by the voltage at REFIN. Connect OUTS to the remote DDR termination bypass capacitors. OUTS is internally connected to OUT through a 12kΩ resistor.SHDNShutdown Control Input. Connect to VCC for normal operation. Connect to analog ground to shut down the linear regulator. The reference bufer remains active in shutdown.PGNDPower Ground. Internally connected to the output sink MOSFET.OUTOutput of the Linear RegulatorINPower Input. Internally connected to the output source MOSFET.EPExposed Pad. Internally connected to AGND.
