  • Low dropout (LDO) voltage regulator with soft-start circuit
    Patent number: 10895884
    Abstract: According to an aspect, a low dropout (LDO) voltage regulator includes a differential amplifier, a pass transistor coupled to an output of the differential amplifier, where the pass transistor is configured to provide an output voltage of the LDO voltage regulator, and a soft-start circuit coupled to the differential amplifier. The soft-start circuit is configured to adjust a soft-start driving signal to control a slope of the output voltage based on the output voltage during a start-up operation of the LDO voltage regulator.

  • Method of forming a semiconductor device
    Patent number: 10775823
    Abstract: In one embodiment, an LDO circuit is configured to increase a bias current to an error amplifier of the LDO circuit, and to subsequently return the bias current to an earlier value in response to the output current increasing to greater than a threshold current level.
