Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 6:
Dropout voltage is the minimum input to output voltage differential may cause permanent damage to the device. Exposure to any Absolute needed to maintain regulation at a specifi ed output current. In dropout, the Maximum Rating condition for extended periods may affect device output voltage will be equal to: VIN – VDROPOUT. reliability and lifetime.
Note 7:
GND pin current is tested with VIN = 2.44V and a current source
Note 2:
The LT3024 is tested and specifi ed under pulse load conditions load. This means the device is tested while operating in its dropout region such that TJ ≅ TA. The LT3024E is 100% tested at TA = 25°C. Performance or at the minimum input voltage specifi cation. This is the worst-case GND at – 40°C and 125°C is assured by design, characterization and correlation pin current. The GND pin current will decrease slightly at higher input with statistical process controls. The LT3024I is guaranteed over the full voltages. Total GND pin current is equal to the sum of GND pin currents –40°C to 125°C operating junction temperature range. from Output 1 and Output 2.
Note 3:
The LT3024 is tested and specifi ed for these conditions with the
Note 8:
ADJ1 and ADJ2 pin bias current fl ows into the pin. ADJ1/ADJ2 pin connected to the corresponding OUT1/OUT2 pin.
Note 9:
SHDN1 and SHDN2 pin current fl ows into the pin.
Note 4:
Operating conditions are limited by maximum junction
Note 10:
Reverse output current is tested with the IN pin grounded and the temperature. The regulated output voltage specifi cation will not apply OUT pin forced to the rated output voltage. This current fl ows into the OUT for all possible combinations of input voltage and output current. When pin and out the GND pin. operating at maximum input voltage, the output current range must be

For the LT3024 dropout voltage will be limited by the minimum limited. When operating at maximum output current, the input voltage input voltage specifi cation under some output voltage/load conditions. range must be limited. See the curve of Minimum Input Voltage in the Typical Performance
Note 5:
To satisfy requirements for minimum input voltage, the LT3024 is Characteristics. tested and specifi ed for these conditions with an external resistor divider (two 250k resistors) for an output voltage of 2.44V. The external resistor divider will add a 5μA DC load on the output. 3024fa 4
