1A Positive Low Dropout

Elektronische Bauelemente

Fixed-Mode Regulator With EN Function

RoHS Compliant Product

Description

The S5U1118 is a low dropout positive fixed-mode regulator with min. 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.S5U1118 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.
