LDO+ regulators do more than just regulate. They include monitor and control functions as well as regulation. The LT3081 has a wide safe area, allowing operation with high currents at high input-output differentials. Output voltage is adjustable from from 0 to
37 volts and it withstands reverse voltage. In addition to regulating, it has a current monitor output, providing an analog output current proportional to the output of the regulator.
