G5E1118 Page: 2/3 ISSUED DATE :2005/07/11 REVISED DATE : Pin Descriptions Name Description GND Ground VOUT The output of the regulator. A minimum of 10uF capacitor must be connected from this pin to ground to insure stability. VIN 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. EN This input pin of regulator. TTL/CMOS compatible input Logic high= disable output, Logic Low or open= output enable. ( internal pull-down resistor~100K). NC No connection.

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.
