• 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.
