Absolute maximum ratings are limiting values above which serviceability may be impaired. 2. Derate PF series 2.8mW/° C when TA>25° C. Derate LS series 2.0mW°C when TA>25° C 3. All MIN/TYP/MAX limits are absolute numbers. Negative signs indicated electrical polarity only. Information furnished by Linear Integrated Systems is believed to be accurate and reliable.
