Abstract:
The present disclosure relates to a voltage regulation circuit including a first transistor connected between an input of voltage to be regulated and an output of a regulated voltage. A first regulation loop controls the first transistor according to a difference between a reference voltage and a first feedback voltage derived from the regulated voltage. A second transistor is connected in series between the first transistor and the output. A second regulation loop controls the second transistor according to a difference between the reference voltage and a second feedback voltage derived from the regulated voltage. The second regulation loop is active in low and high power regulation modes. A switch circuit forces the first transistor into an on state in a low power regulation mode.
