Abstract:
In an embodiment, a voltage regulation circuit includes a regulation circuit with a voltage regulator that provides an output voltage and a control circuit, coupled to the voltage regulator. The control circuit pulls up the output voltage to a reference voltage responsive to the control circuit detecting that a first voltage level of the output voltage is lower than a predefined voltage level. The control circuit decouples the output voltage from the reference voltage responsive to the control circuit detecting that the first voltage level of the output voltage is higher than the predefined voltage level.
