Electrical Characteristics
Note 1: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the de-
vice outside of its rated operating conditions.
Note 2: The LP2975 has internal thermal shutdown which activates at a die temperature of about 150˚C. It should be noted that the power dissipated within the
LP2975 is low enough that this protection circuit should never activate due to self-heating, even at elevated ambient temperatures.
Absolute Maximum Ratings
If Military/Aerospace specified devices are required,
please contact the National Semiconductor Sales Office/
Distributors for availability and specifications.
