„ GENERAL DESCRIPTION
APE1117A is a low dropout positive adjustable or
fixed-mode regulator with minimum of 1A output
current capability.The regulator is able to operate
with output Capacitors as small as 1uF Ceramic
Capacitor for stability.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.
APE1117A is also well suited for other applications
such as VGA cards. APE1117A 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 5.0 with 6.4V to 12V input supply.
