AC Electrical Characteristics
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
beyond its rated operating conditions. Products are not tested under negative Absolute Maximum conditions.
Note 2: The maximum power dissipation must be derated at elevated temperatures and is dictated by T
bient thermal resistance), and T
given in the Absolute Maximum Ratings, which ever is lower. The thermal resistance
Note 3: The human body model is a 100 pF capacitor discharged through a 1.5 k
Note 4: Thermal shutdown will protect the device from permanent damage.
Note 5: For the LM3525-L, OFF is EN
