ABSTRACT:
A system and a method are disclosed for providing a dynamically configured low drop out regulator that has zero quiescent current and a fast transient response. A power supply control circuit is provided that comprises a switcher circuit and a low drop out regulator and a control signal circuit. When the output voltage of the low drop out regulator is in a steady state condition the control signal circuit generates control signals that turn off the operation of the low drop out regulator to provide zero quiescent current. When the output voltage is not in a steady state condition the control signal circuit generates control signals that turn on the operation of the low drop out regulator to provide a fast transient response.
