0V „ Applications • PC peripheral • Communication „ 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 <1.
3V dropout at full load current making it ideal to provide well regulated outputs of 1.
25 to 5.
0 with 6.
3 to 12V input supply.
