GM1117A

ISSUED DATE :2003/08/02 REVISED DATE :2006/06/05C G M 111 7 A Description 1A Low Dropout Positive Adjustable or Fixed-Mode Regulator 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. 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-89 REF. www.DataSheet4U.com A B C D E F Millimeter Min.
