AP1084
5A Low Dropout Positive Adjustable or Fixed-Mode Regulator
Features
General Description
• 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
• Package : TO252, TO263, TO220
AP1084 is a low dropout positive adjustable or fixed-
mode regulator with minimum of 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.

The output of the regulator. 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
I 3 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.
