... OUT pin forced to the rated output voltage. This current flows into the OUT pin and out the GND pin. Note 11: For the LT3024 dropout voltage will be limited by the minimum input voltage specification under some output voltage/load conditions. See the curve of Minimum Input Voltage in the Typical Performance ...

... A bypass capacitor in the range sufficient. The LT3024 regulator is designed to withstand reverse voltages on the IN pin with respect to ground and the OUT pin. In the case of a reverse input, which can happen if a battery is plugged in backwards, the device will act as if there is a diode in series with its input ...

... With 1000pF or larger bypass capacitor on this output, a 6.8 F output capacitor is recommended. The shaded region of Figures 2 and 3 define the regions over which the LT3024 regulator is stable. The minimum ESR needed is defined by the amount of bypass capacitance used, while the maximum ESR is 3 ...

... The ground pin current can be found by examining the GND Pin Current curves in the Typical Performance Char- acteristics section. Power dissipation will be equal to the sum of the two components listed above. The LT3024 regulator has internal thermal limiting de- signed to protect the device during overload conditions For continuous normal conditions, the maximum junction temperature rating of 125 C must not be exceeded ...

... The device will protect both itself and the load. This provides protection against batteries which can be plugged in backward. The output of the LT3024 can be pulled below ground without damaging the device. If the input is left open circuit or grounded, the output can be pulled below ground by 20V. The output will act like an open circuit ...
