General Description
AP1116 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.
AP1116 is also well suited for other applications
such as VGA cards. AP1116 is guaranteed to have
<1.3V dropout at full load current making it ideal to
provide well regulated outputs of 1.25V to 5V with
up to 18V input supply.
1.3V maximum dropout at full load current
Fast transient response
Output current limiting
Built-in thermal shutdown
Packages: SOT89
Good noise rejection
3-Terminal Adjustable or Fixed 1.5V / 1.8V / 2.5V
/ 3.3V / 5.0V
