Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: This IC 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
Note 3: The LTC3035 regulator is tested and specified under pulse load
conditions such that T J ≈ T A . The LTC3035 is 100% production tested at
25 ° C. Performance at –40 ° C and 125 ° C is assured by design,
characterization and correlation with statistical process control.
Note 4: Min Operating Input Voltage required for regulation is:
V IN > V OUT + V DROPOUT and V IN > 1.7V
temperature may impair device reliability.
