Low-Voltage DDR Linear Regulator  
General Description  
Features  
The MAX8794 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  
Internal Power MOSFETs with Current Limit (3A typ)  
Fast Load-Transient Response  
External Reference Input with Reference  
Output Buffer  
1.1V to 3.6V Power Input  
from a low-voltage power input (V = 1.1V to 3.6V). The  
IN  
MAX8794 uses a separate 3.3V bias supply to power the  
control circuitry and drive the internal n-channel MOSFETs.  
The MAX8794 provides current and thermal limits to pre-  
vent damage to the linear regulator. Additionally, the  
MAX8794 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.  
15mV (max) Load-Regulation Error  
Thermal-Fault Protection  
Shutdown Input  
Power-Good Window Comparator with 2ms (typ)  
Delay  
Small, Low-Profile, 10-Pin, 3mm x 3mm TDFN  
Package  
The MAX8794 powers the active-DDR termination bus  
that requires a tracking input reference. The MAX8794  
can also be used in low-power chipsets and graphics  
processor cores that require dynamically adjustable  
output voltages. The MAX8794 is available in a 10-pin,  
3mm x 3mm, TDFN package.
