load. This means the device is tested while operating in its dropout region

or at the minimum input voltage specification. This is the worst-case

GND pin current. The GND pin current decreases slightly at higher input

voltages. Total GND pin current equals the sum of output 1 and output 2

GND pin currents.

Note 8: ADJ1/ADJ2 pin bias current flows into the pin.

Note 9: The LT3029 contains current limit foldback circuitry. See the

Typical Performance Characteristics for current limit as a function of the

Note 10:

SHDN1/SHDN2 pin current flows into the pin.

Note 11: The LT3029 minimum input voltage specification limits dropout

voltage under some output voltage/load conditions. See the curve of

Minimum Input Voltage in the Typical Performance Characteristics.

Note 12: The LT3029 includes overtemperature protection that is intended

to protect the device during momentary overload conditions. Junction

temperature exceeds the maximum operating junction temperature when

overtemperature protection is active. Continuous operation above the

specified maximum operating junction temperature may impair device

reliability.
