products (Note 1)
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.
The input pin of regulator. Typically a large storage capacitor is
connected from this pin to ground to insure that the input voltage does
I 3 not sag below the minimum dropout voltage during the load transient
response. This pin must always be 1.4V higher than Vout in order for the
device to regulate properly.
