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.

OUT
Regulator Input Supply. Bypass IN to GND with a 2.2 μF or greater capacitor.
Regulated Output Voltage. Bypass OUT to GND with a 2.2 μF or greater
capacitor.

SS
ADJ
TRK
Soft Start. A capacitor connected to this pin determines the soft-start time.
Adjust. A resistor divider from OUT to ADJ sets the output voltage.
Track. The output will follow the voltage placed on the TRK pin. (See the
Theory of Operation section for a more detailed description.)
