 General Description

AP1116 is a low dropout positive adjustable or

fixed-mode regulator with minimum of 0.5A 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.

AP1116 is also well suited for other applications

such as VGA cards. AP1116 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 PIN # FUNCTION

Adj (GND) I 1 A resistor divider from this pin to the Vout pin and ground sets the

output voltage. (Ground only for Fixed-Mode)

Vout O 2 The output of the regulator. A minimum of 10uF capacitor must be

connected from this pin to ground to insure stability.

Vin I 3

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.

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 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.

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.
