1A Low Dropout Positive Voltage Regulator  
LM1117-XXXJ3  
Features  
Description  
Adjustable or Fixed Output  
Output Current of 1A  
Low Dropout, 1.4V max at 1A Output Current efficiency. All internal circuitry is designed to  
The LM1117 series of positive adjustable and fixed  
regulators are designed to provide 1A with high  
Good Noise Rejection  
operate down to 1.4V input to output differential.  
The product is specifically designed to provide well-  
regulated supply for low-voltage IC application such  
as high-speed bus termination and low current 3.3V  
logic supply, and other applications such as VGA cards.  
Output Current Limiting  
Built-in Thermal Shutdown  
Fast Transient Response  
Applications
