Note 3:
Operating conditions are limited by maximum junction from 0°C to 125°C operating junction temperature. Specifications over temperature. The regulated output voltage specification will not apply the –40°C to 125°C operating junction temperature range are assured by for all possible combinations of input voltage and output current.

Dropout voltage is the minimum input to output voltage differential temperature will exceed 125°C (LT3010E and LT3010MP) or 140°C needed to maintain regulation at a specified output current. In dropout, the (LT3010H) when overtemperature protection is active. Continuous output voltage will be equal to (VIN – VDROPOUT). operation above the specified maximum operating junction temperature
Note 6:
GND pin current is tested with V may impair device reliability. IN = VOUT (nominal) and a current source load. This means the device is tested while operating in its dropout region. This is the worst-case GND pin current. The GND pin current will decrease slightly at higher input voltages. 30105fe 4 Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Typical Performance Characteristics Pin Functions Applications Information Typical Applications Package Description Revision History Typical Application Related Parts
