ABSTRACT:
A solid state circuit for providing a DC regulated output voltage at an output thereof wherein the circuit exhibits excellent ripple rejection performance to maintain the regulated output voltage constant with perturbations in the supply voltage applied to the circuit. The circuit includes a precision current source for providing output currents to a load circuit which is connected between the current source and ground reference. A bias reference potential is applied to the load circuit which has an output connected to the output of the circuit and a feedback loop for causing the DC regulated voltage to be proportional to the bias reference potential. A frequency compensation circuit is included that is coupled across outputs of the current source which enhances the ripple rejection performance of the circuit to higher frequency component transients of such perturbations in the supply voltage.
