1A Low Dropout Positive Adjustable

www.DataSheet4U.com ISSUED DATE :2005/07/27 REVISED DATE :2006/06/01B G 3 U 111 7 A 1A Low Dropout Positive Adjustable or Fixed-Mode Regulator Description The G3U1117A 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. G3U1117A is also well suited for other applications such as VGA cards. G3U1117A 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 Package Dimensions REF.
