General Description
AP1084 is a low dropout positive adjustable or fixed-mode
regulator with 5.0A 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. AP1084 is also well suited for other
applications such as VGA cards. AP1084 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 3.3V with 4.7 to
12V input supply.
