Powering a BFLY-U3-23S6M-C camera via the GPIO pin 1

I want to power a BFLY-U3-23S6M-C camera via the GPIO pin 1.
The Blackfly U3 Technical Reference (p 24) states that the required voltage is 5V to 24V.
Will the power consumption of the camera, and thus also the CCD sensor temperature, depend on the voltage supplied?
Or to put the question differently: is the internal voltage regulation (to 3.3V I assume) done by a linear voltage regulator of by a switched voltage regulator?
