Abstract
Disclosed is an integrated user programmable slew-rate controlled soft-start for a low-dropout regulator that includes a current steering stage and an integrator stage. The current steering stage may also be denoted as an error amplifier. A Miller compensation capacitor couples between an input node to the integrator stage and an output node for an output voltage of LDO. During a power up period of the LDO, the current steering stage generates an input current that charges the Miller compensation capacitor. This controlled charging of the Miller compensation capacitor controls the slew rate of the output voltage as it rises to its regulated value at a completion of the power up period.
