Voltage regulator

Voltage regulators are found in devices such as computer power supplies where they stabilize the DC voltages used by the processor and other elements. Voltage regulator is actually used to maintain constant voltage level.

Types of voltage regulator

Linear voltage regulatorSwitching voltage regulatorSCR (Silicon Controlled Rectifier)voltage regulator
* Standard Regulator (NPN Darlington)

*LDO (Low Dropout) Regulator

* Quasi Low Dropout Regulator



Switching regulators produces multiple output voltage results from its single input but output voltage are different polarities.

* Buck regulator

* Boost regulator

* Buck-Boost regulator

* Flyback regulator


* SCR series regulator

* SCR parallel regulator
Switching regulators are also categorized by following types:

* Pulse width modulation

* Pulse frequency modulation

* Current mode

* Voltage mode

* Hysteresis
