G 5 U 111 8
1A Positive Low Dropout Fixed-mode Regulator With EN Function
Description
The G5U1118 is a low dropout positive fixed-mode regulator with minimum of 1A 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. G5U1118 is also well suited for other applications such as VGA cards. The product is guaranteed to have <1.4V dropout at full load
current making it ideal to provide well regulated outputs 1.5V to 12V with up to 18V input supply. The product offers a TTL-Logic
compatible enable pin.
