ABSTRACT:
Circuits for regulating a voltage or current to a load(s). In one example, a circuit may include a first amplifier providing an amplifier output signal, the first amplifier having at least a first input and a second input, the first input receiving a voltage reference signal; a first transistor receiving the amplifier output signal, the first transistor having a transistor output; at least one resistor coupled between the transistor output and the second input of the first amplifier and defining a feedback voltage signal node; a second transistor in parallel with the first transistor, the second transistor receiving the amplifier output signal, the second transistor providing a regulated output signal of the circuit; a second amplifier receiving the output signal of the second transistor and the transistor output of the first transistor, the second amplifier providing a control signal; and a circuit element coupled between the feedback voltage signal node and ground, the circuit element receiving as a control the control signal of the second amplifier.
