 Linear regulator - Wikipedia, the free encyclopedia
The transistor (or other device) is used as one half of a potential divider to control the output voltage, and a feedback circuit compares the output voltage to a reference voltage in order to adjust the input to the transistor, thus keeping the output voltage reasonably constant.
Common solid-state series voltage regulators are the LM78xx (for positive voltages) and LM79xx (for negative voltages), and common fixed voltages are 5 V (for transistor-transistor logic circuits) and 12 V (for communications circuits and peripheral devices such as disk drives).
In fixed voltage regulators the reference pin is tied to ground, whereas in variable regulators the reference pin is connected to the centre point of a fixed or variable voltage divider fed by the regulator's output.

 Voltage Dividers
In most cases, the needed voltage is less than the voltage from the main source, so we can use resistors in an appropriate configuration to reduce the voltage from the power source, for use in a small circuit.
Thus, this use of a voltage divider is reasonable and appropriate in some circumstances, but not in all cases.
Thus, even in those cases where a voltage divider by itself is not sufficient to meet the need, it can serve as the basis of a circuit that will perform as required.

 High Voltage Divider
Display or recording equipment, cables attached to the output of the voltage divider, and personnel near the equipment should be isolated from conductive surfaces or leads with a minimum of capacitance to ground to prevent multiple ground returns which can distort the signal.
High voltage resistances are usually 2 megohms or 4 megohms per KV to minimize heating and voltage coefficients consistent with compact sizes.
Preferably the divider should be calibrated with the specific instrument being used and specific proximities if extreme accuracy is required, Greatest accuracy, particularly AC accuracy, is attained with proper ground plane and if maximum clearance to conductive materials, which can cause capacitance variation and corona.

Voltage converters can generate the desired voltage levels, and charge pumps are often the best choice for applications requiring some combination of low power, simplicity, and low cost.
Otherwise, DC voltage levels require the use of active switches, which first charge the capacitor by connecting it across a voltage source and then connect it to the output in a way that produces a different voltage level.
Switching loss is caused by the voltage difference between the flying capacitor and the output capacitor, as well as by on-resistance in the switches.
