Function
Enable;
A low signal disables the IC. A high signal switches it on.
Connect to the input IN, 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 OUT and GND close to the IC terminals, respecting the values
given for

Range”
on
Adjust Input;
Connect an external voltage divider from OUT to GND to determine the output voltage.
By connecting the output pin OUT directly to the adjust pin ADJ without resistors an ouput
voltage equal to the reference voltage VADJ = 1.21 V is determined.
