AP1086 1.5A LOW DROPOUT POSITIVE ADJUSTABLE OR FIXED-MODE REGULATOR Description Pin Assignments (Top View) AP1086 is a low dropout positive adjustable or fixed-mode regulator with 1.5A output current capability. The product is V 3 IN specifically designed to provide well-regulated supply for low voltage IC applications such as high-speed bus termination 2 V OUT and low current 3.3V logic supply. AP1086 is also well suited for other applications such as VGA cards. AP1086 is 1 Adj (GND) guaranteed to have lower than 1.4V dropout at full load Tab is V OUT current making it ideal to provide well-regulated outputs of TO252-3L 1.25V to 5.0V with 4.7 to 12V input supply by different output voltage.

A minimum of 10uF capacitor must be connected V O 2 OUT from this pin to ground to insure stability. The input pin of regulator. Typically a large storage capacitor is connected from this pin to ground to insure that the input voltage does not sag below the V I 3 IN minimum dropout voltage during the load transient response. This pin must always be 1.4V higher than V in order for the device to regulate properly.
