This SVG diagram contains embedded raster graphics. Such images are liable to produce inferior results when scaled to different sizes (as well as possibly being very inefficient in file size). If appropriate to do so, they should be replaced with images created using vector graphics .
Some voltage-regulator tubes contained small amounts of radionuclides to produce a more reliable ionization. [1] The Corona VR tube is a high-voltage version that is filled with hydrogen at close to atmospheric pressure, and is designed for voltages ranging from 400 V to 30 kV at tens of microamperes.
An integrated circuit voltage regulator. A voltage regulator is a system designed to automatically maintain a constant voltage. It may use a simple feed-forward design or may include negative feedback. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC ...
An example op-amp circuit drawn with Klunky and GIMP. Klunky can be used to draw basic circuits, and then a raster editing program like GIMP to modify the screenshots. The Klunky program is public domain, and he has enhanced it with additional components, etc. (See User:Omegatron#Electronics_diagrams. Enhanced version is here.
The LM78S40 from Fairchild is not part of the 78xx family and does not use the same design. It is a component in switching regulator designs and is not a linear regulator like other 78xx devices. The 7803SR from Datel is a full switching power supply module (designed as a drop-in replacement for 78xx chips), and not a linear regulator like the ...
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
The line regulation is important when the input voltage source is unstable or unregulated and this would result in significant variations in the output voltage. The line regulation for an unregulated power supply is usually very high for a majority of operations, but this can be improved by using a voltage regulator.
Series regulators are the more common form; they are more efficient than shunt designs. The series regulator works by providing a path from the supply voltage to the load through a variable resistance, usually a transistor (in this role it is usually termed the series pass transistor); it is in the "top half" of the voltage divider - the bottom half being the load.
