800mA Low Dropout Voltage Regulator  
August 2010  
Rev. 2.1.0  
The SPX1117 is a low power positive-voltage  
regulator designed to satisfy moderate power  
requirements with a cost effective, small  
footprint solution.  
Desktop PC Servers  
Graphic/Video Cards  
Industrial Equipments  
Power Supplies  
This device is an excellent choice for use in  
battery-powered applications and portable  
computers. The SPX1117 features very low  
quiescent current and a low dropout voltage of  
1.1V at a full load. As output current  
decreases, quiescent current flows into the  
load, increasing efficiency. SPX1117 is  
available in adjustable or fixed 1.5V, 1.8V,  
2.5V, 3.3V and 5V output voltages.  
Guaranteed 800mA Output Current  
Guaranteed 1A Peak Current  
Three Terminal Adjustable or Fixed  
1.5V, 1.8V, 2.5V, 3.3V and 5V  
The SPX1117 is offered in 3-pin SOT-223 and  
TO-263 surface mount packages.  
Low Quiescent Current  
Low Dropout Voltage of 1.1V at 800mA  
0.1% Line and 0.2% Load Regulation  
Stable with 2.2µF Ceramic Capacitor  
Overcurrent and Thermal Protection  
An output capacitor of 10µF provides  
unconditional stability while a smaller 2.2µF  
capacitor is sufficient for most applications.  
Lead Free, RoHS Compliant Packages
