The output voltage is set with a single resistor and it is it internally protected against reverse supplies. The current source reference provides constant bandwidth and regulation independent of output voltage.
2.1A LDO+ Regulator Features Cable Drop Compensation and Monitors Current & Temperature
This video explores the LT3086, a new member of our LDO+ family. It provides many functions in addition to regulation. It can monitor and externally limit both temperature and output current, has an accurate power good output, and can compensate for wire drops between the regulator and the load. It sources up to 2.1A of output current and devices can be paralleled to obtain higher output current.
