Exposure to any Absolute needed to maintain regulation at a specified output current. In dropout, Maximum Rating condition for extended periods may affect device the output voltage equals (VIN – VDROPOUT). For the LT3007-1.2 and reliability and lifetime. LT3007-1.5, dropout voltage will be limited by the minimum input voltage. Note 2: The LT3007 is tested and specified under pulse load conditions Note 6: To satisfy minimum input voltage requirements, the LT3007 such that TJ @ TA.
