Note 1:
Stresses beyond those listed under Absolute Maximum Ratings –40°C to 125°C internal operating temperature range. The LTM8001MP may cause permanent damage to the device. Exposure to any Absolute is guaranteed to meet specifications over the full –55°C to 125°C internal Maximum Rating condition for extended periods may affect device operating temperature range. Note that the maximum internal temperature reliability and lifetime. is determined by specific operating conditions in conjunction with board
Note 2:
This μModule regulator includes overtemperature protection that layout, the rated package thermal resistance and other environmental is intended to protect the device during momentary overload conditions. factors. Junction temperature will exceed 125°C when overtemperature protection
Note 4:
No minimum load is required if the respective linear regulator is is active. Continuous operation above the specified maximum operating off, such as when VOUT0 = 0V, VIN45 = 0V, BIAS123 = 0V or BIAS45 = 0V. junction temperature may impair device reliability.
Note 5:
The current limit may decrease to zero at input-to-output
Note 3:
The LTM8001E is guaranteed to meet performance specifications differential voltages greater than 22V. Operation at voltages for VOUT0, from 0°C to 125°C internal. Specifications over the full –40°C to VIN45, BIAS123 and BIAS45 is allowed up to a maximum of 25V as long 125°C internal operating temperature range are assured by design, as the difference between the linear regulator input and output voltage characterization and correlation with statistical process controls. The is below the specified differential voltage. Line and load regulation LTM8001I is guaranteed to meet specifications over the full specifications are not applicable when the device is in current limit.
