com 19-3279; Rev 0; 5/04 KIT ATION EVALU E L B A AVAIL Low-Voltage DDR Linear Regulator General Description Features o Internal Power MOSFETs with Current Limit (3A typ) o Fast Load-Transient Response o External Reference Input with Reference Output Buffer o 1.
1V to 3.
6V Power Input o ±15mV (max) Load-Regulation Error o Thermal Fault Protection o Shutdown Input o Power-Good Window Comparator with 2ms (typ) Delay o Small, Low-Profile 10-Pin 3mm x 3mm TDFN Package o Ceramic or Polymer Output Capacitors MAX1510 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 (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 startup, 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.
Applications Notebook/Desktop Computers DDR Memory Termination Active Termination Buses Graphics Processor Core Supplies Chipset/RAM Supplies as Low as 0.
