Preliminary  
3A Ultra Low Dropout Linear Regulator  
uP7718  
Features  
General Description  
The uP7718 is a 3A ultra low dropout linear regulator † Works with 1.2V~5.5V VIN  
specifically designed for motherboard, notebook and graphic  
„ Adjustable Output Voltage, Down to 0.8V  
„ 1.5% Initial Accuracy  
card applications. This device works with dual supplies, a  
control input for the control circuitry and a power input as  
low as 1.2V for providing current to output. The uP7718  
delivers high-current and ultra-low-drop output voltage as  
low as 0.8V for applications where VOUT is very close to  
VIN.  
„ Excellent Line and Load Regulation  
† 3A Guaranteed Output Current  
„ 178mV @ 3A Dropout Voltage  
† Very Low On-Resistance  
The uP7718 features comprehensive control and protection  
functions: a power on reset (POR) circuit for monitoring  
both control and power inputs for proper operation; an EN  
input for enabling or disabling the device, a power OK with  
time delay for indicating the output voltage status, a  
foldback current limit function, and a thermal shutdown  
function.  
„ 54mtypical  
† VOUT Pull Low Resistance when Disabled  
† VOUT Power OK Signal  
† Fast Transient Response  
† Low External Component Count  
† Low Cost and Easy to Use  
The uP7718 is available in PSOP-8 package with very low  
thermal resistance.  
† Enable Pin  
† Over Current and Over Temperature Protection  
† RoHS Compliant and Halogen Free  
Applications  
† Desktop PCs, Notebooks, and Workstations  
† Graphic Cards  
Ordering Information  
† Low Voltage Logic Supplies

uP7718ASU8 PSOP-8  
Remark  
† Microprocessor and Chipset Supplies  
† Split Plane Microprocessor Supplies  
† Advanced Graphics Cards Supplies  
† SoundCards and Auxiliary Power Supplies  
† SMPS Post Regulators  
Note: uPI products are compatible with the current IPC/  
JEDEC J-STD-020 requirement. They are halogen-free,  
RoHS compliant and 100% matte tin (Sn) plating that are  
suitable for use in SnPb or Pb-free soldering processes.
