AP1116  
0.5A Low Dropout Positive Adjustable or Fixed-Mode Regulator (Preliminary)  
General Description  
Features  
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.  
1.3V maximum dropout at full load current  
Fast transient response  
Output current limiting  
Built-in thermal shutdown  
Packages: SOT89  
Good noise rejection  
3-Terminal Adjustable or Fixed 1.5V / 1.8V / 2.5V

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.
