Claim Text:
1. A linear power regulator device, comprising: an external connection configured to connect to an external pass device connected between a power source and an external load, and arranged to regulate a power provided by said power source to said external load if said external connection is connected to the external pass device; an internal pass device configured to connect between the power source and the external load, and arranged to regulate said power at least when said external connection is not connected to the external pass device; and a driver device having a driver output connected to the external connection and the internal pass device, the driver device being arranged to drive both the internal pass device and the external pass device via the driver output wherein, in operation, the internal pass device only provides power to the load when the driver device applies a voltage that exceeds a threshold voltage, the threshold voltage being larger than a voltage at a control input of the external pass device when a current flows through the external pass device.
