A min. of 10uF capacitor must be connected from this pin to ground to insure stability. VIN EN NC 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. http://www.SeCoSGmbH.com/ 01-Jun-2002 Rev.

Line and load regulation are measured at a constant juction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead =1/8" from the package. 2: Line and load regulations are guaranteed up to the max. power dissipation of 15W. Power dissipation is determined by the input/ output differential and the output current. Guaranteed max. power dissipation will not be available over the full input/output range. 3: Quiescent current is defined as the min. 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. http://www.SeCoSGmbH.com/ 01-Jun-2002 Rev.
