G5E1286
The G5E1286 is 1.5A 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.

Pin Descriptions
Name Adj (Gnd) Vsense Vin I I I/O Description A resistor divider from this pin to the Vout pin and ground sets the output
voltage. (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 la...
