SPX3940  
1A Low Dropout Voltage Regulator  
February 2012  
Rev. 1.0.0  
GENERAL DESCRIPTION  
APPLICATIONS  
The SPX3940 is a 1A, accurate voltage  
regulator with a low drop out voltage of  
280mV (typical) at 1A.  
ñ Power Supplies  
ñ LCD Monitors  
ñ Portable Instrumentation  
ñ Medical and Industrial Equipments  
These regulators are specifically designed for  
low voltage applications that require a low  
dropout voltage and a fast transient response.  
They are fully fault protected against over-  
current, reverse battery, and positive and  
negative voltage transients.  
FEATURES  
ñ Guaranteed 1.5A Peak Current  
ñ 1% Output Accuracy SPX3940A  
ñ Low Quiescent Current  
The SPX3940 is offered in 3-pin SOT223 and  
TO-263 packages. For a 3A version, refer to  
the SPX29300 data sheet.  
ñ Low Dropout Voltage of 280mV at 1A  
ñ Extremely Tight Load and Line  
Regulation  
ñ Extremely Fast Transient Response  
ñ Reverse-battery Protection  
ñ Internal Thermal Protection  
ñ Internal Short Circuit Current Limit  
ñ Replacement for LM3940  
ñ Standard SOT223 & TO-263 packages
