General Description
AP1120 series are low dropout positive 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/2.5V or 3.3V/1.8V logic supply. AP1120 series
are guaranteed to have <1.3V dropout at full load
current making it ideal to provide well regulated
outputs dual channels with up to 18V input supply.

The output of the regulator. A
minimum of 10uF capacitor
(0.15Ω ≤ ESR ≤ 20Ω) must
be connected from this pin to
ground to insure stability.
The input pin of regulator.
Typically a large storage
capacitor (0.15Ω ≤ ESR ≤
20Ω) is connected from this
pin to ground.
