IC voltage regulators are three-terminal devices that provide a constant DC output voltage that is independent of the input voltage, output load current, and temperature.

Voltage regulators are power converters that provide voltage control capabilities.

Power supplies are devices that produce AC or DC power.

Voltage and current signal conditioners amplify or modulate AC or DC current or voltage and process signals to improve transmission

Transient voltage surge suppressors protect against temporary excess voltage and/or current in an electrical circuit that has been disturbed

Motor controllers receive supply voltages and provide signals to motor drives that are interfaced to motors.

Power or line conditioners regulate, filter, and suppress noise in AC power for sensitive computer and other solid state equipment
