AP1115
0.6A LOW DROPOUT POSITIVE ADJUSTABLE
OR FIXED-MODE REGULATOR
Description
Pin Assignments
AP1115 is a low dropout positive adjustable or fixed mode regulator
AP1115A
with 0.6A 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. 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 Descriptions
Pin Name
I/O
Function
Adj (GND)
I
A resistor divider from this pin to the VOUT pin and ground sets the output voltage (Ground only for FixedMode).
VOUT
O
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.
VIN
I
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.

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.
