Description
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.
