1A Low Dropout Positive Adjustable or Fixed-Mode
Regulator
The G1117A is a low dropout at positive adjustable or fixed-mode
regulator with minimum of 1A output current capability. The product is specifically designed to provide well-regulated supply for low voltage IC applications such as high-speed bus termination and low current 3.3V logic supply. G1117A is also well suited for other applications such as VGA cards. G1117A is guaranteed to have lower than 1.4V dropout at full load current making it ideal to provide well-regulated outputs of 1.25 to 5.0 with 6.4V to 12V input supply.
