The 78xx Series, a Fixed Output Voltages Regulators

The 78xx seriesis designed to output one voltage level, as they come in 5v, 6v, 7v, 8v,78xx Adjustable Output Regulator (7 to 30V)9v, 10v, 12v, 15v, 20v, and 24v fixed output voltages and can output up to 1A of current as a positive voltage regulator. You can use these series for application requirements up to 150mA.
The 78XX series of voltage regulatorsare designed for positive input. The “xx” indicates the output voltage of the device as generally the series named e.g 7805, 7806, 7807, 7809, 7810, 7812, 7815, 7820, and 7824 and depend on every manufacturers for differing naming schemes.

But there is space to tweakthe 78xx seriessuch they can deliver over 1A output current or need to obtain adjustable voltages and currents even this device mainly asa fixed voltage regulators, follow each datasheet for this purpose. Or you may see one ofFairchild’svariation on 78′s family here at http://www.hqew.net/circuit-diagram/The-78xx-Series$2c-a-Fixed-Output-Voltages-Regulators_5312.html
We also? provide you with informations if you have questions about78 series regulatorsuch as can a higher voltage be output with a lower input voltage, output voltage drops when a load is connected, what diodes need to connect for preventing damage because of higher output than input voltage, kind of external capacitor should be used, and etc. Find it here.
