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. GL1117A is also well suited for other applications such as VGA cards. GL1117A 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 15V input supply. Features 1.4Vmaximum dropout full load current Fast transient response Output current limiting Built-in thermal shutdown Good noise rejection 3-Terminal Adjustable or Fixed 1.5V,1.8V,2.5V,3.3V,5.0V Applications PC peripheral Communication Package Dimensions SOT-223 REF.
