LT3483 Linear Technology, LT3483 Datasheet - Page 2

• Manufacturer Part Number: LT3483
• Description: Inverting Micropower DC/DC Converter
• Manufacturer: Linear Technology

ABSOLUTE AXI U RATI GS
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LTC3483E is guaranteed to meet specifications from 0°C to
70°C. Specifications over the –40°C to 85°C operating temperature range
are assured by design, characterization and correlation with statistical
process controls.
