Manufacturers : Power supplies : Voltage regulators

A voltage regulator is a switching power supply that supplies a steady, typically low, voltage to a load. Voltage regulators, such as DC to DC converters, are used to provide stable voltage sources for electronic systems. Voltage regulators regulate the external power supplied to the internal circuitry so that the current usage or quiescent power is efficient. Typically, a voltage regulator is used for supplying an output voltage with a regulated voltage level from a DC voltage source by appropriately controlling a duty cycle of a power switch transistor. Switching voltage regulators are known to be an efficient type of DC to DC converter. A switching regulator generates an output voltage by converting an input DC voltage into a high frequency voltage, and filtering the high frequency voltage to generate the output DC voltage. A voltage regulator maintains a level output voltage despite variations in power supply voltage or current drawn by a load. These regulators typically output a relatively high voltage. The high voltage regulators use a transformer or possibly another similar device to increase the supply voltage to the desired high voltage for driving the load. Applications of these high voltage regulators include charging a photoflash capacitor, such as those commonly used in cameras. Low dropout voltage regulators are widely used building blocks in almost any electronic application. They adapt an external power supply to the needs of the supplied circuit. In portable applications as in mobile phones a main requirement for the voltage regulator is a low dropout voltage and a good stability over a large range of capacitive loads. Central processing unit (CPU) voltage regulators receive one voltage and supply a second voltage to a processor, also known as a microprocessor. A CPU voltage regulator may supply 1-2 volts to the microprocessor from a 12-volt input.
