(1)

The typical value includes one standard deviation (sigma) at nominal operating condition.

(2)

High-side LDO supports full external load (IH) only up to TA = 85

℃. See the Isolated DC/DC Converter section for more details.

(3)

THD is the ratio of the rms sum of the amplitues of first five higher harmonics to the amplitude of the fundamental.

(4)

Offset error temperature drift is calculated using the box method, as described by the following equation:

(5)

Gain error temperature drift is calculated using the box method, as described by the following equation:
