ABSTRACT:
A current limited low dropout voltage circuit for coupling between first and second power supply terminals and an output terminal for providing a current limited low dropout voltage output having a MOS pass transistor coupled in series between the first power supply terminal and the output terminal, a drive circuit coupled to the gate of the MOS pass transistor, circuitry for limiting the gate-source voltage of the MOS pass transistor to limit the maximum current therethrough to a first maximum current level when the voltage between the second power supply terminal and the output terminal is less than a predetermined value, and circuitry for limiting the gate-source voltage of the MOS pass transistor to limit the maximum current therethrough to a second maximum current level when the source to drain voltage of the MOS pass transistor is greater than a predetermined voltage difference and the voltage between the output terminal and the second power supply terminal is greater than the predetermined value, the second maximum current level being greater than the first maximum current level.
