  "textContent": "A power control circuit includes: a lithium-ion capacitor (LIC) charged by power supplied by an power source; a first protection circuit supplying, to a first load operating using power supplied by the external power source, a first discharge current of the LIC when the power is no longer supplied from the power source; and a second protection circuit supplying, to a second load operating using the power, a second discharge current of the LIC when the power is no longer supplied. The second load operates at a lower power consumption than the first load. The first protection circuit stops supplying the first discharge current to the first load when a voltage of the LIC becomes less than a first voltage. The second protection circuit stops supplying the second discharge current to the second load when the voltage becomes less than a second voltage being lower than the first voltage.",
