Abstract:
A voltage regulator comprising:(a) an error amplifier having a first input coupled to a first reference voltage, a second input receiving a feedback signal, and an output producing a first control signal;(b) an output transistor having a gate, a drain coupled to an unregulated input voltage, and a source coupled to produce a regulated output voltage on an output conductor;(c) a feedback circuit coupled between the output conductor and a third reference voltage, the feedback circuit producing the feedback signal;(d) a capacitor coupled between the output of the error amplifier and the gate of the output transistor; and(e) a servo amplifier having a first input coupled to receive a second reference voltage, a second input coupled to the output of the error amplifier, and an output coupled to the gate of the output transistor to produce a second control signal thereon.
