products (Note 1)
AP1115 is a low dropout positive adjustable or fixed mode
regulator 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
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 Fixed-Mode).
Vout
O
The output of the regulator. A minimum of 10uF capacitor (0.15Ω ≤ ESR 20) must be
connected from this pin to ground to insure stability.
The input pin of regulator. Typically a large storage capacitor (0.15Ω ≤ ESR 20) is
Vin
I
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.
