Function
Enable;
A low signal disables the IC. A high signal switches it on.
Connect to the input I, if enable functionality is not required.
Input voltage;
IC supply. For compensating line influences, a capacitor close to the IC pins is recommended.
Ground
Output voltage;
Connect a capacitor between Q and GND close to the IC terminals, respecting the values
given for its capacitance CQ and ESR given in the table “Functional Range” on Page 8
Adjust Input;
Connect an external voltage divider from Q to GND to determine the output voltage.
By connecting the output pin Q directly to the adjust pin ADJ without resistors an ouput
voltage equal to the reference voltage VADJ = 1.21 V is determined.
