 Basically the same as the 78xx regulator, but adjustable. It also has three pins: input, output, adjust. A voltage divider (2 resistors) is connected to the output pin and ground to create a reference voltage. This reference voltage is connected to the adjust pin. The regulator will adjust the output voltage, until the reference voltage is 1.25V. By altering one of the resistors of the voltage divider, you can adjust the output voltage. Basically the same as the 78xx regulator, but adjustable. It also has three pins: input, output, adjust.
