EP1084
5A Low Dropout Linear Regulator
Description
EP1084 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.
EP1084 is also well suited for other applications
such as VGA cards. EP1084 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.
• Output current limiting
• Adjustable output voltage or fixed 1.5V, 1.8V,
2.5V, 3.3V, 5.0V
• Good noise rejection
• 1.4V maximum dropout at full load current
• Built-in thermal shutdown
• Fast transient response
• Packages: TO252, TO263
Applications
• PC peripheral
• Low Voltage Logic Supplies
• Post Regulator for Switching Power Supply
