ABSTRACT:
A voltage generator circuit which is capable of preventing the generation of a through current in a transition to a power-down mode to reduce current consumption. The voltage generator circuit includes a voltage generator activated by a reference voltage to generate an output voltage. A reference voltage clamp circuit is coupled to the voltage generator for clamping the reference voltage to a first voltage in response to a power-down signal to deactivate the voltage generator. An output voltage clamp circuit is coupled to the voltage generator for clamping the output voltage to a second voltage. A control circuit is coupled to the output voltage clamp circuit for enabling the output voltage clamp circuit after the voltage generator is deactivated in response to the power-down signal.
