ELECTRICAL CHARACTERISTICS

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: The RUN pin is internally clamped to 5V

Note 3: The LTM8027E is guaranteed to meet performance specifications

from 0°C to 125°C internal operating temperature. Specifications over

the full –40°C to 125°C internal operating temperature range are assured

by design, characterization and correlation with statistical process

controls. The LTM8027I is guaranteed to meet specifications over the full

The

–40°C to 125°C internal operating temperature range. The LTM8027MP

is guaranteed to meet specifications over the full –55°C to 125°C

internal operating range. Note that the maximum internal temperature is

determined by specific operating conditions in conjunction with board

layout, the rated package thermal resistance and other environmental

factors.

Note 4: The maximum continuous output current may be derated by the

LTM8027 junction temperature.
