µVRMS

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. 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 VOUT0 = 0V, VIN45 = 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 VOUT0,

VIN45, BIAS123 and BIAS45 is allowed up to a maximum of 36V 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.
