Electronics - voltage regulator

[dvn]

The voltage regulator have 3 legs, 2 for input and one for output to make a constant voltage.

I was wondering if this is possible?

2 x input of 12v and can the output be 24v or only under 12v?

thanks

If you're talking about the 78xx series voltage regulators, then one of the legs is common. You need to reference the input and output voltages with respect to the common.

From what I've known, regulator outputs are always less than the inputs. If you're looking for a way to increase a voltage, then you may want to look into DC-DC converters.

Yes, it is possible for a voltage regulator to have 3 legs, with 2 for input and one for output. The purpose of a voltage regulator is to maintain a constant output voltage regardless of changes in the input voltage. This means that it can take in an input of 12v and output a constant voltage of either 12v or 24v, depending on the specific voltage regulator. Some voltage regulators may also have the capability to output a voltage higher than the input voltage, but this would depend on the specific design and capabilities of the regulator. It is important to carefully read the specifications and limitations of the voltage regulator before use to ensure that it is suitable for your specific needs.
