General Description
AP1117 is a low dropout positive adjustable or
fixed-mode regulator with minimum of 1A 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.
AP1117 is also well suited for other applications
such as VGA cards. AP1117 is guaranteed to have
<1.3V dropout at full load current making it ideal to
provide well regulated outputs of 1.25 to 5.0 with 6.3
to 12V input supply.

FUNCTION
A resistor divider from this pin to the Vout pin and ground sets the
output voltage. (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 1.3V higher than Vout
in order for the device to regulate properly.
