Pb PART OBSOLETE - NO ALTERNATE PART AP1086 Lead-Free 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 specifically V 3 IN designed to provide well-regulated supply for low voltage IC applications such as high-speed bus termination and low current 3.3V 2 V OUT 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 1 Adj (GND) 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. Tab is V OUT TO252-3L Features (Top View) 3 V 3-Terminal Adjustable or Fixed 1.5V, 1.8V, 2.5V,3.3V, 5.0V IN 1.4V Maximum Dropout at Full Load Current 2 V OUT Fast Transient Response Built-in Thermal Shutdown 1 Adj (GND) Output Current Limiting Lead Free Packages: TO252-3L, TO263-3L, TO220-3L Tab is V OUT TO252-3L, TO263-3L, and TO220-3L: Available in Green TO263-3L Molding Compound (No Br, Sb) Totally Lead-Free RoHS Compliant (Notes 1 & 2) (Top View) For automotive applications requiring specific change 3 control (i.e. parts qualified to AEC-Q100/101/200, PPAP V IN capable, and manufactured in IATF 16949 certified facilities), 2 V OUT please contact us or your local Diodes representative. 1 Adj (GND) - AP1086 Pin Descriptions Pin Name I/O Pin Description Adj (GND) 1 Adjustable (Ground only for fixed mode) The output of the regulator. A minimum of 10uF capacitor must be connected from this pin to V O 2 OUT 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 V I 3 IN transient response. This pin must always be 1.4V higher than V in order for the device to OUT regulate properly.
