The term "low dropout regulator" refers to a regulator that is capable of regulating close to the input voltage. They don't require the input voltage to be much higher than the output voltage like some regulators do.
For example, if you need to charge a battery at 14 volts, an ordinary regulator might need 16 or 17 volts input. A low dropout regulator might need only 15 volts to do the job.
