AP1120 series are low dropout positive regulator to provide 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/2.5V or
3.3V/1.8V logic supply. AP1120 series are guaranteed to have
<1.3V dropout at full load current making it ideal to provide well
regulated outputs dual channels with up to 18V input supply.

Pin Descriptions
NAME
FUNCTION
GND1/2
Ground
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.
The input pin of regulator.
Typically a large storage
capacitor (0.15Ω ≤ ESR ≤
20Ω) is connected from this
pin to ground.

3.
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.
4. Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by
the input/output differentially and the output current. Guaranteed maximum power dissipation will not be available over the
full input/output range.
5. Quiescent current is defined as the minimum output current that requires maintaining regulation. At 12V input/output
differential the device is guaranteed to regulate if the output current is greater than 10mA.
6. Vout1 and Vout2 are connected to the PCB copper area 5.5mm*5.5mm separately. If you need large PD or lower Tc & Tj,
please connect to the large copper area >> 5.5mm*5.5mm (like 10mm*10mm).
