G3U1085
3A Low Dropout Positive Adjustable or Fixed-Mode
Regulator
The G3U1085 is a low dropout positive adjustable or fixed-mode
regulator with minimum of 3A 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. G3U1085 is also well suited for other applications such as VGA cards. G3U1085 is guaranteed to have <1.4V dropout at full load current making it ideal to provide well-regulated outputs of 1.25 to 5.0V with 4.7 to 12V input supply by different output voltage.
