FEATURES
DESCRIPTION
1.5V Maximum Dropout at Full Load Current
Fast Transient Response
Output Current Limiting
Built-in Thermal Shutdown
Good Noise Rejection
Need only 1uF Capacitor for Stability
Low-ESR Ceramic Capacitor Required for

APE1117A 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. APE1117A is also well suited for other applications
such as VGA cards. APE1117A 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.

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 DESCRIPTIONS
PIN SYMBOL
ADJ/GND
PIN DESCRIPTION
A resistor divider from this pin to the VOUT pin and ground sets the output voltage.
(Ground only for Fixed-Mode)
VOUT
The output of the regulator. A minimum of 1uF capacitor ( 10mΩ < ESR < 1Ω)
must be connected from this pin to ground to insure stability.
VIN
The input pin of regulator. A minimum of 1uF 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 1.5V
higher than VOUT in order for the device to regulate properly.
