AP1086 1.5A LOW DROPOUT POSITIVE ADJUSTABLE OR FIXED-MODE REGULATOR Features • • • • • • • 3-Terminal Adjustable or Fixed 1.5V, 1.8V, 2.5V,3.3V, 5.0V 1.4V Maximum Dropout at Full Load Current Fast Transient Response Built-in Thermal Shutdown Output Current Limiting Packages: TO252-3L, TO263-3L, and TO220-3L Lead Free Finish/RoHS Compliant for Lead Free products (Note 1) General Description AP1086 is a low dropout positive adjustable or fixed-mode regulator with 1.5A 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. AP1086 is also well suited for other applications such as VGA cards. AP1086 is guaranteed to have lower than 1.4V dropout at full load current making it ideal to provide well-regulated outputs of 1.25V to 5.0V with 4.7 to 12V input supply by different output voltage.

A minimum of 10uF capacitor must be connected 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 minimum dropout voltage during the load transient response. This pin must always be 1.4V higher than Vout in order for the device to regulate properly.
