Abstract: One example discloses a voltage regulator, including: a power supply input; a regulated voltage output; an output transistor coupled to the power supply input and the regulated voltage output; and a current amplifier coupled between the power supply input and the regulated voltage output; wherein the current amplifier is configured to supply a second current from the power supply input to the regulated voltage output when a first current between the power supply input and the output transistor exceeds a threshold current.

Abstract: Embodiments of a method and a device are disclosed. In an embodiment, a method for discharging an output capacitor of a power supply is disclosed. The power supply includes a primary side for receiving a signal to be converted and a secondary side for outputting a converted signal. The method involves detecting whether synchronous rectification (SR) circuitry at the secondary side is inactive, determining that the primary side is disconnected from a mains voltage when the SR circuitry is detected to be inactive, and discharging an output capacitor at the secondary side based on the determination that the primary side is disconnected from the mains voltage.
