Bias current draw of HV9910B PWM controller is very low?

Page 4 of the HV9910B datasheet says it draws about 2mA of bias current (i am not including the FET drive current here).

Can it really be this low?

Surely the internal linear regulator alone would draw more bias current than that?

Seems correct. It is probably all CMOS so not much current. The regulator can only supply 5 ma. max (including external loads) so the 2 ma sound about right for the internals.
