No one seems to sell a simple, cheap 5-volt regulated power supply.

Only the most advanced equipment used expensive and bulky regulated power supplies.

The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost.

Or from inadequately regulated power supplies.

A regulated power supply is an embedded circuit,it converts unregulated ac into a constant dc.

If a non regulated power supply is used, the magnetic flux will degrade, as the resistance of the coil goes up.

Regulated power supply.

As mentioned previously, neither Radio Shack nor Jameco seem to offer a standard, inexpensive 5-volt regulated power supply.

An example of this kind of use would be a DC error amplifier used in a regulated power supply circuit feedback loop system.

The output from the regulated power supply may be alternating or unidirectional, but is nearly always DC (Direct Current).

Therefore some Atom enthusiasts removed and by-passed the internal regulators and powered their Atoms from an external 5 V regulated power supply.

He made significant contributions to room acoustics, regulated power supply, lightweight phonograph pickups and electronic reproduction equipment, and notably, during World War II, in sonar.

They are often used as part of a simple regulated power supply for higher currents: a transformer generates a voltage which, when rectified, is a little higher than that needed to bias the linear regulator.

A TWT integrated with a regulated power supply and protection circuits is referred to as a traveling-wave-tube amplifier (abbreviated TWTA and often pronounced "TWEET-uh").

Many tracks use banks of lead-acid batteries to produce sufficient high amp DC power, but in recent years, relatively inexpensive high-quality electronically regulated power supplies have become more popular to achieve consistent and clean power.

A regulated power supply is one that controls the output voltage or current to a specific value; the controlled value is held nearly constant despite variations in either load current or the voltage supplied by the power supply's energy source.

A TWTA consists of a traveling-wave tube coupled with its protection circuits (as in klystron) and regulated power supply Electronic Power Conditioner (EPC), which may be supplied and integrated by a different manufacturer.

The following circuits are simplified conceptual circuits only, real world circuits also require a smoothed or regulated power supply, heater for the filaments (the details depending on if the selected valve types are directly or indirectly heated), and the cathode resistors are often bypassed, etc.
