VARIABLE INPUT VOLTAGE REGULATOR
摘要:
A variable input voltage regulator includes a first circuit configured to convert a first voltage from a first voltage source to a first current, and a second circuit electrically coupled to the first circuit and configured to mirror the first current to a voltage output node. The variable input voltage regulator further includes a third circuit electrically coupled to the voltage output node of the second circuit and configured to supply additional current to the voltage output node from a second voltage of a second voltage source in response to a control input.
