WIDE VOLTAGE RANGE LOW DROP-OUT REGULATORS |
摘要 |
In one embodiment, the present disclosure includes a low drop-out regulator circuit comprising a pass transistor providing an output voltage on an output terminal in response to a gate voltage on a gate of the pass transistor. A feedback circuit is coupled to the output terminal to generate a feedback voltage, and an error amplifier provides a drive signal in response to a reference voltage and the feedback voltage. A first gate driver circuit is operable over a first voltage range to provide the gate voltage to the pass transistor in response to the drive signal. A second gate driver circuit is operable over a second voltage range to provide the gate voltage to the pass transistor in response to the drive signal, where the second voltage range is lower than the first voltage range. |
