G5E1284

www.DataSheet4U.com ISSUED DATE :2005/05/24 REVISED DATE :2006/03/29B G5E1284 The G5E1284 is 4A regulator with extremely low dropout voltage. This product is specifically designed to provide well regulated supply for applications requiring 2.8V or lower voltages from 3.3V ATX power supplies where high efficiency of the switch can be achieved without the cost and complexity associated with switching regulator. One such application is the new graphic chipsets that requires anywhere from 2.4V to 2.7V supply. 4A Ultra Low Dropout Positive Adjustable or Fixed-mode Regulator Description Features Package Dimensions 0.7V maximum dropout voltage at 4A load current Built-in thermal shutdown Output current limiting Adjustable or fixed output voltage 1.5V,1.8V,2.5V,3.3V,5.0V Fast transient response Good noise rejection REF.

(Gnd only for fixed mode) The pin is the positive side of the reference that allows remote load sensing to achieve excellent load regulation. A minimum of 10uF capacitor must be connected from this pin to ground to insure stability. The input pin of regulator. Typically a ...
