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
–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.
Note 5: V IN voltages below the start-up threshold (7.5V) are only
supported when BIAS1 is externally driven above 6.5V.
