General Description
AP1119 is a low dropout positive adjustable or
fixed-mode regulator with minimum of 0.5A 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.
AP1119 is also well suited for other applications
such as VGA cards. AP1119 is guaranteed to have
<1.3V dropout at full load current making it ideal to
provide well regulated fixed outputs of 1.5 to 12V
with up to 18V input supply. The AP1119 offers a
TTL – Logic compatible enable pin.
