S8 PART MARKING
The q denotes specifications which apply over the full operating
temperature range.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired
Note 2: At input voltages > 3.6V and ambient temperatures >70
°C,
continuous power dissipation must be derated to maintain junction
temperatures below 125
°C. Derate 6mW/°C above 70°C in SO-8.
Note 3: The LTC1516 is tested with the capacitors shown in Figure 1.
