1A Low Dropout Positive Adjustable or Fixed-Mode Regulator
Description
The GM1117A 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. GM1117A is also well
suited for other applications such as VGA cards. GM1117A 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.
