(3) The maximum continuous output current (I
OUT
) is determined by device power dissipation limitations. Continuous short circuit operation
at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150°C
(4) Drift determined by dividing the change in parameter at temperature extremes by the total temperature change.
(5) Negative input current implies current flowing out of the device.
