AP1117  
1A Low Dropout Positive Adjustable or Fixed-Mode Regulator  
Features  
General Description  
AP1117 is a low dropout positive adjustable or  
fixed-mode regulator with minimum of 1A 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.  
AP1117 is also well suited for other applications  
such as VGA cards. AP1117 is guaranteed to have  
lower than 1.4V dropout at full load current making  
it ideal to provide well-regulated outputs of 1.25 to  
5.0 with 6.4V to 12V input supply.  
- 1.4V maximum dropout at full load current  
- Fast transient response  
- Output current limiting  
- Built-in thermal shutdown  
- Packages: SOT223, TO263, TO252, TO220,  
SOT89  
- Good noise rejection  
- 3-Terminal Adjustable or Fixed 1.5V, 1.8V, 1.9V,  
2.5V, 3.3V, 5.0V  
Applications  
- PC peripheral  
- Communication
