1A LOW DROPOUT POSITIVE ADJUSTABLE OR
FIXED-MODE REGULATOR
General Description
Features
AP1117 is a low dropout positive adjustable or fixed-mode
regulator with 1A output current capability. The product is voltage
specifically designed to provide well-regulated supply for low
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
18V input supply. AP1117 is available in commercial temperature
grade.

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 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.

Notes:
4. 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.
5. Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the difference
between input and output differential and the output current. Guaranteed maximum power dissipation will not be available over the full
input/output range.
6. 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.
7. Test conditions for SOT89-3L, TO220-3L, TO252-3L and TO263-3L: Devices mounted on FR-4 substrate, single sided PC board, 2oz copper,
with minimum recommended pad layout, no air flow. The case point of θJC is located on the thermal tab.
8. Test conditions for SOT223-3L: Devices mounted on FR-4 substrate, single sided PC board, 2oz copper, with 5mmx5mm thermal pad layout, no
air flow. The case point of θJC is located on the thermal tab.
