1 1 1 EN Enable Input. Drive EN high to turn on the regulator; drive it low to turn off the regulator. For automatic startup, connect EN to IN. 2 2 2 IN Regulator Input Supply. Bypass IN to GND with a 2.2 μF or greater capacitor. 3 3 3 OUT Regulated Output Voltage. Bypass OUT to GND with a 2.2 μF or greater capacitor. 4 SS Soft Start. A capacitor connected to this pin determines the soft-start time. 4 ADJ Adjust. A resistor divider from OUT to ADJ sets the output voltage. 4 TRK Track. The output will follow the voltage placed on the TRK pin. (See the Theory of Operation section for a more detailed description.) 5, 6, 7, 8 5, 6, 7, 8 5, 6, 7, 8 GND Ground.
