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
lower than 1.4V dropout at full load current making
it ideal to provide well-regulated outputs of 1.25 to
5.0 with 6.4V 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 (0.15
ESR 20) must be connected from this pin to ground to insure
stability.
The input pin of regulator. Typically a large storage capacitor
(0.15Ω ≤ ESR 20) 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.
