Abstract:
1. A voltage regulator circuit comprising: a regulator input terminal configured to receive power from a regulator input voltage source; an error amplifier comprising a positive input terminal configured to receive a reference voltage; a reference voltage circuit comprising a reference voltage output terminal and a reference common terminal, wherein the reference voltage output terminal is connected to the positive input terminal; an offset voltage circuit configured to supply a voltage offset difference between the reference common terminal and a ground potential terminal; a regulator output terminal configured to deliver a current to a load at a regulated voltage substantially independent of a plurality of voltage transients on the regulator input voltage source and substantially independent of a plurality of current transients on the regulator output terminal; a current controlled output transistor (CCOT) comprising: a voltage controlled driver transistor (VCDT) comprising: an output voltage sensor configured to sense at least a portion of the regulated voltage between the regulator output terminal and the reference common terminal, where a voltage at the output voltage sensor is compared with a voltage at the reference voltage output terminal by the error amplifier, the error amplifier being configured to generate a control signal that is applied to the third VCDT electrode.
