SSC1118
1A Positive Low Dropout
Elektronische Bauelemente
RoHS Compliant Product
Fixed-Mode Regulator With EN Function
Description
The SSC1118 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 highspeed bus termination and low current 3.3V logic supply.SSC1118 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.

Description
The output pin of regulator. A min. of 10uF capacitor must be connected from this pin to ground to insure stability. The input pin of regulator. Typically a large storage capacitor is connected from this pin to ground to insure that the input voltage does not sag below the min. dropout voltage during the load transient response. This pin must always be1.3V higher than VOUT in order for the device to regulate properly. This input pin of regulator. TTL/CMOS compatiable input Logic high= disable output, Logic low or open=output enable. (internal pull-down resistor~100K) No connection.
