Abstract
A dual voltage generation circuit, responsive to a switching signal, to selectively generates a constant voltage at an output terminal is provided. The generation circuit comprises a switch transistor, a first and a second zener diodes and a diode. As the switching signal is logic high, at the output terminal, the circuit outputs a first constant voltage, and as the switching signal is logic low, the circuit outputs a second constant voltage.
