Claim:
1. A linear voltage regulator device, comprising: an external connection connectable, or connected, 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 connectable between the power source and the external load, and arranged to regulate said power when said external connection is not connected to the external pass device; a driver device having a variable transconductance and arranged to drive the internal pass device and arranged to drive the external pass device via the external connection; and a transconductance control circuitry arranged to control the variable transconductance to change depending on an output current flowing through the internal pass device and/or the external pass device, wherein the driver device has a first mode with a first transconductance and a second mode with a second transconductance and the transconductance control circuitry is configured to control the driver device to be in the first mode or the second mode depending on the output current flowing through one or more of the internal pass device and the external pass device transconductance.
