●
Adjustable or Fixed Output  
The LM1117 series of positive adjustable and fixed  
regulators are designed to provide 1A with high  
efficiency. All internal circuitry is designed to  
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 of 1A  
Low Dropout, 1.4V max at 1A Output Current  
Good Noise Rejection  
Output Current Limiting  
Built-in Thermal Shutdown  
●
●
Fast Transient Response  
Can operate using MLCCs in the capacitance range  
of 2μF to 10μF

Note : 1.See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured at  
a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead 1/18” from the  
package.  
2. Line and load regulation are guaranteed up to the maximum power dissipation of 6.7W. Power dissipation is determined by the  
difference in input and output and the output current. Guaranteed maximum power dissipation will not be available over the full  
input/output range.
