GE1084
5A Low Dropout Positive Adjustable or Fixed-Mode Regulator
Description
The GE1084 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. GE1084 is also well suited for other
applications such as VGA cards. GE1084 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.
Features
Ԧ1.5V maximum dropout at full load current
ԦBuilt-in thermal shutdown
ԦOutput current limiting
ԦAdjustable output voltage or fixed 1.5V,1.8V,2.5V,3.3V,5.0V
ԦFast transient response
ԦGood noise rejection

The input pin of regulator .Typically a large storage capacitor is connected from this pin to ground
to insure that the input voltage does not sag below the minimum dropout voltage during the load
transient response .This pin must always be 1.5V higher than Vout in order for the device to
regulate properly.
