2. Voltage regulator - Wikipedia

   en.wikipedia.org/wiki/Voltage_regulator

   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 ...

3. Voltage-regulator tube - Wikipedia

   en.wikipedia.org/wiki/Voltage-regulator_tube

   Schematic representation of a cold cathode voltage-regulator tube 5651 Regulator tube in operation. A voltage-regulator tube (VR tube) is an electronic component used as a shunt regulator to hold a voltage constant at a predetermined level. Physically, these devices resemble vacuum tubes, but there are two main differences:

4. Power supply unit (computer) - Wikipedia

   en.wikipedia.org/wiki/Power_supply_unit_(computer)

   Diagram of a typical XT and AT voltage regulator circuit Internals of a PSU with passive PFC (left) and active PFC (right) The desktop computer power supply converts the alternating current (AC) from a wall socket of mains electricity to a low-voltage direct current (DC) to operate the motherboard, processor and peripheral devices.

5. 78xx - Wikipedia

   en.wikipedia.org/wiki/78xx

   The 78xx line are positive voltage regulators: they produce a voltage that is positive relative to a common ground. There is a related line of 79xx devices which are complementary negative voltage regulators. 78xx and 79xx ICs can be used in combination to provide positive and negative supply voltages in the same circuit.

6. Voltage regulator module - Wikipedia

   en.wikipedia.org/wiki/Voltage_regulator_module

   A voltage regulator module (VRM), sometimes called processor power module (PPM), is a buck converter that provides the microprocessor and chipset the appropriate supply voltage, converting +3.3 V, +5 V or +12 V to lower voltages required by the devices, allowing devices with different supply voltages be mounted on the same motherboard.

7. Low-dropout regulator - Wikipedia

   en.wikipedia.org/wiki/Low-dropout_regulator

   Low-dropout (LDO) regulators operate similarly to all linear voltage regulators.The main difference between LDO and non-LDO regulators is their schematic topology.Instead of an emitter follower topology, low-dropout regulators consist of an open collector or open drain topology, where the transistor may be easily driven into saturation with the voltages available to the regulator.

8. Regulated power supply - Wikipedia

   en.wikipedia.org/wiki/Regulated_power_supply

   A regulated power supply is an embedded circuit; it converts unregulated AC (alternating current) into a constant DC. With the help of a rectifier it converts AC supply into DC. Its function is to supply a stable voltage (or less often current), to a circuit or device that must be operated within certain power supply limits.

9. Linear regulator - Wikipedia

   en.wikipedia.org/wiki/Linear_regulator

   Despite their name, linear regulators are non-linear circuits because they contain non-linear components (such as Zener diodes, as shown below in the simple shunt regulator) and because the output voltage is ideally constant (and a circuit with a constant output that does not depend on its input is a non-linear circuit).
