Claim 11:
12. A power supply unit for an aerosol generation device, the power supply unit comprising:
an internal power supply configured to hold power supplied to a heater configured to heat an aerosol source;
a connector connectable to an external power supply;
a controller configured to control power supply from the internal power supply to the heater;
a first transistor of a dropper type positioned on a first power supply path between the connector and a positive electrode of the internal power supply; and
a Schottky diode,
wherein a current from the connector is supplied to a source of the first transistor, and a current from a drain of the first transistor is supplied to the positive electrode of the internal power supply, and
the controller performs feedback control on a voltage of a gate of the first transistor based on a current or a voltage supplied from the first transistor, thereby adjusting power supplied from the external power supply to the internal power supply, and
an anode of the Schottky diode is connected to the drain of the first transistor, and a cathode of the Schottky diode is connected to the source of the first transistor.
