Abstract
A voltage regulator for use in controllable bus terminators providing a source and a sink to a regulated output without clamping circuitry is disclosed. The regulator maintains a voltage at a node by sourcing current into the node when a cable line sinks current from the node and sinking current from the node when a cable line sources current into the node. By avoiding the use of clamping circuitry, a voltage deadband between the regulator output voltage and the clamp circuit voltage is avoided.
