GL1147-50

www.DataSheet4U.com ISSUED DATE :2004/12/06 REVISED DATE : G L 11 4 7 - 5 0 The GL1147-50 is a low dropout at positive 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 logic supply. GL1147-50 is also well suited for other applications such as VGA cards .GL1147-50 is guaranteed to have lower than 1.4V dropout at full load current making it ideal to provide well-regulated outputs 5.0V with 6.4V to 12V input supply.
