(Preliminary) EP1084

5A Low Dropout Linear RegulatorFeatures Description

• 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 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.
