Abstract
A voltage regulator circuitry () adapted to operate in a high-temperature environment of a turbine engine is provided. The voltage regulator may include a constant current source () including a first semiconductor switch () and a first resistor () connected between a gate terminal (G) and a source terminal (S) of the first semiconductor switch. A second resistor () is connected to the gate terminal of the first semiconductor switch () and to an electrical ground (). The constant current source is coupled to generate a voltage reference across the second resistorA source follower output stagemay include a second semiconductor switch () and a third resistor () connected between the electrical ground and a source terminal of the second semiconductor switch. The generated voltage reference is applied to a gating terminal of the second semiconductor switch ().
