Description
AP1086 is a low dropout positive adjustable or fixed-mode
regulator with 1.5A 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. AP1086 is also well suited
for other applications such as VGA cards. AP1086 is
guaranteed to have lower than 1.4V dropout at full load
current making it ideal to provide well-regulated outputs of
1.25V to 5.0V with 4.7 to 12V input supply by different output
voltage.

The output of the regulator. A minimum of 10uF capacitor must be connected
from this pin to ground to insure stability.
V

I 3
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 1.4V higher than V
OUT
in order for the device to regulate properly.

Notes: 2. See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured at a constant
junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18” from the package.
3. Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the difference in input and
output and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range.
4. Quiescent current is defined as the minimum output current required in maintaining regulation. At 12V input/output differential the device is
guaranteed to regulate if the output current is greater than 10mA.
