General Description
AP1119 is a low dropout positive adjustable or
fixed-mode regulator with minimum of 0.5A 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.
AP1119 is also well suited for other applications
such as VGA cards. AP1119 is guaranteed to have
<1.3V dropout at full load current making it ideal to
provide well regulated fixed outputs of 1.5 to 12V
with up to 18V input supply. The AP1119 offers a
TTL – Logic compatible enable pin.
1.3V maximum dropout at full load current
Fast transient response
Output current limiting
Built-in thermal shutdown
Packages: SOT89-5L
Good noise rejection
5-Terminal device with fixed 1.5V, 1.8V, 2.5V,
3.3V, 5.0V, 9.0V, 12V output.

NAME
FUNCTION
GND
Ground
Vout
The output of the regulator. A minimum of 10uF capacitor must be connected from this pin
to ground to insure stability.
Vin
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.
EN
The input pin of regulator. TTL/CMOS compatible input Logic high = disable output, Logic
Low or open =Enable output. (internal Pull-down resistor ~ l00K).

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 5W. Power dissipation is determined by the
input/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 maintain regulation. At 12V input/output differential the
device is guaranteed to regulate if the output current is greater than 10mA.
