AP1115
0.6A LOW DROPOUT POSITIVE ADJUSTABLE
OR FIXED-MODE REGULATOR
Description
Pin Assignments
The AP1115 is
a
low dropout positive adjustable or fixed
AP1115A
mode regulator with 0.6A output current capability. The product is
specifically designed to provide a well-regulated supply for low-voltage
IC applications such as high-speed bus termination and low-current
3.3V logic supply. AP1115 is also well suited for other applications such
as VGA cards. AP1115 is guaranteed to have <1.3V dropout at full load
current, making it ideal to provide well regulated outputs of 1.25V to 5V
with up to 18V input supply.

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 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.

Notes:
4. 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.
5. 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.
