Note 1:
Stresses beyond those listed under Absolute Maximum Ratings The LTC2050C/LTC2050HVC are guaranteed to meet the temperature may cause permanent damage to the device. Exposure to any Absolute limits of 0°C and 70°C. The LTC2050I/LTC2050HVI are guaranteed to meet Maximum Rating condition for extended periods may affect device the temperature limits of –40°C and 85°C. The LTC2050H/LTC2050HVH reliability and lifetime. are guaranteed to meet the temperature limits of –40°C and 125°C. The
