AP1117
1A LOW DROPOUT POSITIVE ADJUSTABLE OR
FIXED-MODE REGULATOR
General Description
Features
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)
Adj (GND)

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.

Vin
O

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.

Notes: 2. 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.
3. 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.
4. 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.
