IN

EN
Regulator Input Supply. Bypass IN to GND with a 2.2 μF or greater capacitor.
Ground.
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.

SS
Soft Start. Connect a capacitor between SS and GND to set the output
start-up time.
Adjust. A resistor divider from OUT to ADJ sets the output voltage.
Bypass. Connect a 1 nF or greater capacitor (10 nF recommended)
between BYP and GND to reduce the internal reference noise for low
noise applications.
Track. The output follows the voltage placed on the TRK pin. (See the
Theory of Operation section for a more detailed description.)
