ABSTRACT:
Voltage regulator circuitry is provided. The voltage regulator circuitry may contain a drive transistor that is controlled by the output of an operational amplifier. The drive transistor may supply a regulated voltage to a load. The operational amplifier may compare a reference voltage and a feedback signal at its inputs. The operational amplifier may include first and second stages. An adjustable resistor may be provided between the first and second stages. Control circuitry may control the resistance of the adjustable resistor based on the amount of current flowing through the load to ensure stable operation of the voltage regulator circuitry. Overshoot and undershoot detection and compensation circuitry may compensate for overshoot and undershoot in the regulated voltage. Voltage ramp control circuitry may be used to control the ramp rate of the regulated voltage.
