Ans.

Types of voltage regulators include linear regulators, switching regulators, and shunt regulators.

Linear regulators: provide a stable output voltage by dissipating excess power as heat (e.g. LM317)
Switching regulators: more efficient than linear regulators by switching the input voltage on and off (e.g. LM2596)
Shunt regulators: regulate voltage by shunting excess current to ground (e.g. TL431)
