... OUT pin forced to the rated output voltage. This current flows into the OUT pin and out the GND pin. Note 11: For the LT3023 dropout voltage will be limited by the minimum input voltage specification under some output voltage/load conditions.

... The ADJ1 and ADJ2 pin voltage is 1.22V referenced to ground and the output voltage range is 1.22V to 20V. BYP1/BYP2 (Pins 5/1): Bypass. The BYP1/BYP2 pins are used to bypass the reference of the LT3023 regulator to achieve low noise performance from the regulator. The BYP1/BYP2 pins are clamped internally to 0.6V (one V ) from ground ...

... The device is protected against both reverse input and reverse output voltages. In battery backup applications where the output can be held backup battery when the input is pulled to ground, the LT3023 acts like it has a diode in series with its output and prevents reverse current flow. Additionally, in dual supply applications where the ...

... U U APPLICATIO S I FOR ATIO Output Capacitance and Transient Response The LT3023 regulator is designed to be stable with a wide range of output capacitors. The ESR of the output capaci- tor affects stability, most notably with small capacitors. A minimum output capacitor with an ESR less is recommended to prevent oscilla- tions ...

... W U dissipation from both channels must be considered dur- ing thermal analysis. The LT3023 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 important to give careful consideration to all sources of thermal resistance from junction to ambient ...

... IN(MAX) and the load. This provides protection against batteries which can be plugged in backward. The output of the LT3023 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; no current will flow out of the pin ...

... Current flow back into the output will follow the curve shown in Figure 6. When the IN pin of the LT3023 is forced below the OUT1 or OUT2 pins or the OUT1/OUT2 pins are pulled above the IN pin, input current will typically drop to less than 2 A. ...
