APE1117
1A LOW DROPOUT LINEAR REGULATOR
DESCRIPTION
APE1117 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. APE1117 is also well suited for other applications
such as VGA cards. APE1117 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.

Temperature Stability
Note1: 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.
Note2: 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.
Note3: 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.

PIN DESCRIPTION
A resistor divider from this pin to the V
OUT
pin and ground sets the output voltage.
(Ground only for Fixed-Mode)
The output of the regulator. A capacitor ( 0.15Ω < ESR < 1Ω) must be connected
from this pin to ground to insure stability.
The input pin of regulator. Typically a large storage capacitor (0.15Ω < ESR < 1
Ω)
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.
