Assignee: SILEGO TECHNOLOGY INC.
Field: Control (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A low-dropout regulator, comprising: a transconductor configured to drive an output voltage at an output node of the low-dropout regulator;
a capacitor coupled to the output node of the low-dropout regulator;
an error amplifier configured to generate an input current during a start-up of the low-dropout regulator to charge the capacitor,
wherein the error amplifier includes a current digital-to-analog converter configured to generate a tail current during the start-up of the low-dropout regulator, and
a slew rate configuration circuit configured to generate a digital code to the current digital-to-analog converter, and wherein the current digital-to-analog converter is configured to convert the digital code to form the tail current to control a slew of the output voltage.
