can a voltage regulator deliver an output higher than its input? Answered

can a voltage regulator deliver an output higher than its input? for instance if i had a 12v power supply would a 15v voltage regulator be able to output 15v? i am thinking of making a variable power supply and wanted to know if a 12 DC adaptor would be enough for larger voltages

Yup. They're call step-up regulators.

No, a standard linear regulator can't generate more than its input !

A SWITCHING regulator can boost the voltage though.
