voltage regulator

[′vōl·tij ‚reg·yə‚lād·ər]
(electronics)
A device that maintains the terminal voltage of a generator or other voltage source within required limits despite variations in input voltage or load. Also known as automatic voltage regulator; voltage stabilizer.

voltage regulator

An electronic circuit used to maintain a level amount of voltage in an electrical line. It eliminates power surges, spikes and brownouts, which can cause harm to sensitive electronics. A voltage regulator "module" (VRM) is a voltage regulator in a replaceable unit.

Voltage Regulators and Stabilizers
Regulators and stabilizers do the same thing. However, voltage regulators generally deal with output from DC power sources, whereas voltage stabilizers and conditioners typically maintain AC line voltage. See surge suppression and UPS.

The electrical circuit diagram of the ac voltage regulator (test circuit) is shown in Figure 5(a), where the source ac voltage [V.sub.S] was 220 V; the load R, L was a group of 100 W light bulbs connected in parallel, where their impedance values are in Table 2.
In this study, the proposed AC voltage regulator is also aimed to regulate the input voltage in sudden fluctuations.
This is because the bridge and filter capacitor voltage is likely to allow the unregulated dc voltage with a cripple voltage be the input to voltage regulator. By grounding the ac ripple, the output voltage of the IC regulator can be maintained at the required specifications.
A manufacturer's defect has led to internal failures of voltage regulators, NSN 611001-559-2092, PN N3221.
Products include protective relays, voltage regulators, gen-set controllers, custom transformers and digital excitation control systems.
Integrated Device Technology Inc (IDT) (Nasdaq:IDTI), an analogue and digital company providing essential mixed-signal semiconductor solutions, announced on Tuesday that it has delivered voltage regulator modules (VRMs) to SGI.
Deep discharging Hawkers in cold environments can also shorten their life span because the current voltage regulator will undercharge them.
"Often these higher voltages are seen in applications such as LCD bias control, DC bias adjustments of power amplifiers, gain and offset trim of amplifiers, laser diode bias control and voltage regulator output control."
The amplifier is a single bias design incorporating an internally protected voltage regulator. Noise figure is 4.5 dB typical.
From all appearances, the alternator current was feeding the charge system directly without much intervention by a voltage regulator. At Oshkosh, I stopped by the vendor booth.
The LVR-7815 is a 15 Volts positive fixed voltage regulator. Each unit is 100 percent tested for all grades and across one of three standard temperature ranges: 0 to +70[degrees]C; -40 to +100[degrees]C; -55 to +125[degrees]C.
