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: This μModule regulator includes overtemperature protection that
is intended to protect the device during momentary overload conditions.
Junction temperature will exceed 125°C when overtemperature protection
is active. Continuous operation above the specified maximum operating
junction temperature may impair device reliability.
Note 3: The LTM8001E is guaranteed to meet performance specifications
from 0°C to 125°C internal. 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
LTM8001I is guaranteed to meet specifications over the full
–40°C to 125°C internal operating temperature range. The LTM8001MP
is guaranteed to meet specifications over the full –55°C to 125°C internal
operating temperature 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: No minimum load is required if the respective linear regulator is
off, such as when V
OUT0
= 0V, V
IN45
= 0V, BIAS123 = 0V or BIAS45 = 0V.
Note 5: The current limit may decrease to zero at input-to-output
differential voltages greater than 22V. Operation at voltages for V
OUT0
,
V
IN45
, BIAS123 and BIAS45 is allowed up to a maximum of 25V as long
as the difference between the linear regulator input and output voltage
is below the specified differential voltage. Line and load regulation
specifications are not applicable when the device is in current limit.
