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 both commercial and
industrial temperature grade.

A resistor divider from this pin to the Vout pin and ground sets the output voltage
(Ground only for Fixed-Mode).
Vout
O
2
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.
3
The input pin of regulator. Typically a large storage capacitor (0.15Ω ≤ ESR ≤ 20Ω)
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.

AP1117 contains an internal thermal limiting circuit that is designed to protect the regulator in the event that the maximum junction temperature
exceeded. When activated, typically at 150°C, the regulator output switches off and then back on as the die cools.

5. 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.
6. 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.
7. 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.
8. Test condition for SOT223: Ta=27°C, no air flow, 2 oz copper, 5mmx5mm pad.
9. Test condition for TO252: Ta=27°C, no air flow, 2 oz copper, 5mmx5mm pad.
10. Test condition for SOT89-3L: no air flow, no heat sink.
11. Test condition for TO220-3L: with copper area of approximately 3in2, 1 oz, no air flow.
12. Test condition for TO263-3L: with copper area of approximately 2cmX2cm, 1 oz, no air flow.
