Hi team,
2 question about ADJ:
- How does it work when the ADJ is less than 2V? (Disable?)
- Is it a problem to apply voltage to ADJ when VIN is 0V?
Kind regards,
Goto

Hi Goto-san,
Question 1:
From the Electrical Characteristics Table:
ADJ pin below 0.7 V will disable the output.
ADJ pin above 2 V will enable the output.
ADJ pin between 0.7 V and 2 V is not guaranteed to be either enabled or disabled. The output will turn on between 0.7 V and 2 V, but we do not guarantee turn-on for all conditions until ADJ pin reaches 2 V.
Question 2:
No, that is not a problem.
From the Absolute Maximum Ratings table:
ADJ - IN voltage should be limited to 18 V.
Vadj - Vin = 18 V (limit).
If Vin = 0 V, then ADJ voltage up to 18 V is acceptable.
Best,
Eric
