Note 3:
The LTC3035 regulator is tested and specified under pulse load of a device may be impaired. conditions such that TJ ≈ TA. The LTC3035 is 100% production tested at
Note 2:
This IC includes overtemperature protection that is intended to 25°C. Performance at –40°C and 125°C is assured by design, protect the device during momentary overload conditions. Junction characterization and correlation with statistical process control. temperature will exceed 125°C when overtemperature protection is active.
Note 4:
Min Operating Input Voltage required for regulation is: Continuous operation above the specified maximum operating junction VIN > VOUT + VDROPOUT and VIN > 1.7V temperature may impair device reliability. 3035f 2
