... OUT pin. In the case of a reversed input, which occurs with a battery plugged in backwards, the LT3008 acts blocking diode is in series with its input. No reverse current fl ows into the LT3008 and no reverse voltage appears at the load. The device protects both itself and the load ...

... In battery backup applications, where a backup battery holds up the output when the input is pulled to ground, the LT3008 acts blocking diode is in series with its output and prevents reverse current fl ow. In applications where the regulator load returns to a negative supply, the output can be pulled below ground by as much as 50V without affecting startup or normal operation ...

... Table 1 to prevent contamination from causing unwanted shifts in the output voltage. Output Capacitance and Transient Response The LT3008 is stable with a wide range of output capaci- tors. The ESR of the output capacitor affects stability, most notably with small capacitors. Use a minimum output capacitor of 2.2μ ...

... Carefully consider all sources of thermal resistance from junction to ambi- ent including other heat sources mounted in proximity to the LT3008. For surface mount devices, heat sinking is accomplished by using the heat spreading capabilities of the PC board and its copper traces. Copper board stiffen- ...
