Package : TO252, TO263, TO220
RoHS Compliant
APE1085 is a low dropout positive adjustable or
fixed-mode regulator with minimum of 3.0A 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.
APE1085 is also well suited for other applications
such as VGA cards. APE1085 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
3.3V with 4.7 to 12V input supply.

The output of the regulator. A minimum of 10uF (0.15Ω ≤ ESR

stability.
The input pin of regulator. Typically a large storage capacitor (0.15
ESR 20) is connected from this pin to ground to insure that the

during the load transient response. This pin must always be 1.4V
(1.3V) higher than Vout in order for the device to regulate properly.
