5A Low Dropout Positive Adjustable or Fixed-Mode Regulator Description
The PL1084 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.
PL1084 is also well suited for other applications such as VGA cards.
PL1084 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.

Pin Descriptions
Name Adj (Gnd) Vout I/O Pin# 1 2 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.
