General Description

AP1086 is a low dropout positive adjustable or

fixed-mode regulator with minimum of 1.5A 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.

AP1086 is also well suited for other applications

such as VGA cards. AP1086 is guaranteed to have

<1.4V dropout at full load current making it ideal to

provide well-regulated outputs of 1.25V to 5.0V with

4.7 to 12V input supply by different output voltage.
