1. A powered surgical instrument, comprising:
a first circuit portion operable at a first voltage level;
a second circuit portion operable at a second voltage level, wherein the second voltage level is different from the first voltage level;
a voltage source to supply the first voltage level to supply power to electrical components in the first circuit portion;
a transistor comprising a control terminal, a first conduction terminal, and a second conduction terminal, wherein the first conduction terminal is coupled to the voltage source;
a control circuit coupled to the control terminal of the transistor, the control circuit to:
set the transistor in a linear mode; and
control the transistor to set a current for operating a motor.
