NOT RECOMMENDED FOR NEW DESIGN USE AZ1084C AP1084 5A LOW DROPOUT POSITIVE ADJUSTABLE OR FIXED-MODE REGULATOR General Description Features          1.4V Maximum Dropout at Full Load Current Built-in Thermal Shutdown Output Current Limiting Adjustable Output Voltage or Fixed 1.5V, 1.8V, 2.5V, 3.3V, 5.0V Fast Transient Response Good Noise Rejection Lead Free Packages: TO252-3L, TO263-3L and TO220-3L TO252-3L, TO263-3L and TO220-3L: Available in “Green” Molding Compound (No Br, Sb) Lead Free Finish/RoHS Compliant (Note 1) AP1084 is a low dropout positive adjustable or fixed-mode regulator with 5.0A 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. AP1084 is also well suited for other applications such as VGA cards. AP1084 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.

VOUT O 2 The output of the regulator. A minimum of 10uF (0.15Ω ≤ ESR ≤ 20Ω) capacitor must be connected from this pin to ground to insure stability. 3 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 (1.3V) higher than VOUT in order for the device to regulate properly.
