AP1118
1A Positive Low Dropout Fixed-Mode Regulator With EN Function
Features
General Description
AP1118 is a low dropout positive 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. AP1118 is also
well suited for other applications such as VGA
cards. AP1118 is guaranteed to have <1.4V
dropout at full load current making it ideal to provide
well regulated outputs of 1.25 to 12V with up to 18V
input supply. The AP1118 offers a TTL – Logic
compatible enable pin.

NAME
FUNCTION
GND
Ground.
The output of the regulator. A minimum of 10uF capacitor must be connected from this pin
to ground to insure stability.
Vout
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.
Vin
The input pin of regulator. TTL/CMOS compatible input Logic high = disable output, Logic
Low or open = output enable. (internal pull-down resistor~100 K).

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
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 to maintain regulation. At 12V input/output differential the
device is guaranteed to regulate if the output current is greater than 10mA.
