Classification: CPC G | IPC G

Claim 8:
9. A method of controlling a slew rate of an output voltage of a low-dropout regulator during a power up period of the low-dropout regulator, comprising:
converting a digital code in a current digital-to-analog converter to form the tail current;
steering the tail current through a first transistor in a transistor pair of an error amplifier during the power up period; mirroring the tail current to form an input current to a capacitor coupled to an output node of the low-dropout regulator; and charging the capacitor with the input current to control the slew rate of the output voltage as the output voltage rises from zero volts at an initiation of the power up period to a regulated value at a completion of the power up period.
