Description

AP1086 is a low dropout positive adjustable or fixed-mode

regulator with 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 lower than 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.
