Abstract
In one implementation, an apparatus includes a first input terminal configured to receive a bias voltage, the bias voltage received from a low-dropout voltage regulator (LDO) error amplifier, and a second input terminal configured to receive a supply voltage; a first output terminal configured to supply a feedback voltage, the feedback voltage supplied to the LDO error amplifier, and a second output terminal configured to supply regulated power to an associated load; a regulating portion configured to regulate power supplied to the associated load; and a switching portion configured to enable or disable the load from receiving the regulated power.
