NOTES:
(1) Low output currents, below the continuous conduction threshold will cause an increase in output voltage
beyond the load regulation limit. For Application circuit 16935F see the regulation curve on sheet 5.
(2) All VID codes not specifically listed here are invalid and cause shutdown exactly as if the shutdown pin had
been asserted. xxxxx refers to any valid VID code.
(3) This device is ESD sensitive. Use of standard ESD handling precautions is required.
