www.DataSheet4U.com ISSUED DATE :2005/07/27 REVISED DATE :2006/03/29C G3U1084 5A Low Dropout Positive Adjustable or Fixed-Mode Regulator The G3U1084 is a low dropout positive adjustable or fixed mode regulator with minimum of 5.0A 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. G3U1084 is also well suited for other applications such as VGA cards. G3U1084 is guaranteed to have lower than 1.5V dropout at full load current making it ideal to provide well regulated outputs of 1.25 to 3.3V with 4.7 to 12V input supply. Description Features Package Dimensions 1.5V maximum dropout at full load current Built-in thermal shutdown Output current limiting Adjustable output voltage or fixed 1.5V,1.8V,2.5V,3.3V,5.0V Fast transient response Good noise rejection REF.
