GJ1084
5A Low Dropout Positive Adjustable or Fixed-Mode Regulator
Description
The GJ1084 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. GJ1084 is also well suited for other
applications such as VGA cards. GJ1084 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
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

Function
Adjustable (Ground only for fixed mode)
The output of the regulator. A minimum of 10uF capacitor must be connected from this pin to
ground to insure stability.
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.
