G5E1118
1A Positive Low Dropout Fixed-mode Regulator With EN Function
Description
The G5E1118 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. G5E1118 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
Ground
GND
The output of the regulator. A minimum of 10uF capacitor must be connected from this pin to ground to insure stability.
V
OUT
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 minimum dropout voltage during the load transient response .This pin must always be 1.3V
higher than VOUT in order for the device to regulate properly.
VIN
This input pin of regulator. TTL/CMOS compatible input Logic high= disable output, Logic Low or open= output enable.
( internal pull-down resistor~100K).

Note 1: See thermal regulation specifications for charges in output voltage due to heating effects. Line and load regulation are measured
at a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead=1/8” from the
package.
Note 2: Line and load regulations are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the
input/output differential and the output current. Guaranteed maximum power dissipation will not be available over the full
input/output range
Note 3: Quiescent current is defined as the minimum output current required to maintain regulation. At 12V input/output differential the
device is guaranteed to regulate if the output current is greater than 10mA.
