Note 1:
Absolute Maximum Ratings are limits beyond which damage to the device may occur. For guaranteed performance limits and associated test
conditions, see the Electrical Characteristics tables.
Note 2:
To ensure constant junction temperature, low duty cycle pulse testing is used.
Note 3:
Limits appearing in

Note 4:
The maximum allowable power dissipation is a function of the maximum junction temperature T
(MAX), the junction-to ambient thermal resistance
θ
J-A
and the ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is calculated using:

Where the values of the junction-to-ambient thermal resistances are as follows: 220

Note 5:
Dropout Voltage is defined as the input to output differential at which the output voltage drops 100mV below its nominal value measured at 1V
differential.
Note 6:

Threshold Voltage levels are specified as a percentage of input voltage V
