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 LTM4601AHV is tested under pulsed load conditions such
that TJ ≈ TA. The LTM4601AHVE is guaranteed to meet performance
specifications from 0°C to 85°C. Specifications over the –40°C to 85°C
operating temperature range are assured by design, characterization
and correlation with statistical process controls. The LTM4601AHVI is
guaranteed over the –40°C to 85°C operating temperature range. The
LTM4601AHVMP is guaranteed and tested over the –55°C to 125°C
operating temperature range. For output current derating at high
temperature, please refer to Thermal Considerations and Output Current
Derating discussion.
Note 3: Remote sense amplifier recommended for ≤3.3V output.
Note 4: 100% tested at wafer level only.
Note 5: See output current derating curves for different VIN, VOUT and TA.
